Apple ANCS with CC2540 (11)

Got a BLE112 Shield 2.0 from Seeedstudio to learn about ANCS. 

Apple ANCS with CC2540 (10)

I found slackhappy on github who had sucessfuly made ANCS connection use BLE112

 

Apple ANCS with CC2540 (9)

1.I think it is still the Bonding problem.

2.From the picture on http://mbientlab.com/blog/ancs-demo-on-the-sensortag/ you will find out the device show on the bluetooth list need to Pair and after pair it will show a (i) icon . Just like normal bluetooth device.

3.But my connection is just "Not Pair" to "Connected" no asking for Pair and no (i) icon.

4.I don't know how to do that in CC2540. I will switch to nRF51822 next week.

 

Apple ANCS with CC2540 (8)

1.I follow the mbientlab.com's method. Modify the code.

2.The iOS and CC2540 can connect.

3.When it is bond I start the Discovery function.

4.It found the UUID of  ANCS

5.It found the UUID of Notification

6.I got the handle (I hope so) . The value is 0x10.

7.I Write 0x0001 to the handle.

8.I got Write Error 5.

PS. The Image's error is Error 3 because I mess up the handle value.

PS. I put the code I modify here -> Download TimeApp.zip

PS.My Board has Key. So I use Key_Up for Adv and press connect on iOS . After Connect I use Key_Right to Set Notify.

PS.I was wrong. The program still don't create the bond. Don't use the code.

Apple ANCS with CC2540 (7)

I found a cool page that descript how to do ANCS on CC2541.

http://mbientlab.com/blog/ancs-on-ti2541-in-an-afternoon/

Apple ANCS with CC2540 (6)

1.I have to go back to the begining . How to let iOS  connect to CC2540 and then Switch CC2540 Role from Peripheral to Central without break the Link.

2.There is a MasterSlaveSwitch demo code use 1.2 Stack. But I cannot compile it and it seems will break the Link during switch role. But it is a good starting point to learn how to Merge 2 role .

3.Pepple use CC2640 -> It support BT2 and BT4 (Need firmware upgrade). There are even less data on CC2640.

4.Will hang on CC2540 for a while . Mabye switch to nRF51822 after Chinese New Year if my CC2540 no progress has been made. (nRF51822 provide sample code to connect to ANCS)

TI Forum:

Alternate between Central and Peripheral roles

Apple ANCS with CC2540 (5)

I can subscript to SimpleBLEPeripheral's 0xFFF3 Notification. 

But I CANNOT subscript to Apple's ANCS Notification.

No clue. 

The possible problem is on the "Bonding". When I use LightBlue on iPhone 4 (6.1)  my iPad Mini (Run ANCS Program) will ask for Pair. If I remove the Pairing on Bluetooth Setting. My LightBlue won't work with ANCS anymore . I have to Restart LightBlue and re-Pairing then it work with ANCS.  

Best Reference TI's Forum 

Apple ANCS with CC2540 (4)

1.I try to set the Notification but it fail, So I fall back to connect to SimpleBLEPeripheral . It is also not easy,too. Beacuse there are few example on how to set Notification and most of them are not correct.

2.I make a few mistake on a)Got the wrong Charateristic UUID of 0xFFF4 it is 0x002f instead of 0x002e b)I should use GATT_WriteCharValue() instead of GATT_WriteNoRespon() c)req.cmd = 0, not 1;

3.Next step is to parse the Notification Message and try to port to ANCS

PS.The "MSG: 7" on the LCD Screen means, it has got 7 Notification. (BLEPeripheral will send out notification every 5 seconds)

PS.Another problem of why it is hard to debug is I cannot tell if BLEPeripheral has really got my Command from BLECentral. I don't know where to put my Log 

PS.The most useful ulr is this one.TI China Support Forum. 

Apple ANCS with CC2540 (3)

1.The UUID is in reverse order. 

#define APPLE_NOTIFICATION_SERV_UUID_128N        {0x79,0x05,0xf4,0x31,0xb5,0xce,0x4e,0x99,0xa4,0x0f,0x4b,0x1e,0x12,0x2d,0x00,0xd0}

This is the Normal one

#define APPLE_NOTIFICATION_SERV_UUID_128R        {0xd0,0x00,0x2d,0x12,0x1e,0x4b,0x0f,0xa4,0x99,0x4e,0xce,0xb5,0x31,0xf4,0x05,0x79}

This is the Reverse one

 

2.Now I can find 3 Charateristic , next step is to learn how to use the Notification .

 

3.nRF51822 got sample code for ancs. Maybe I should switch side. ....

 

 

nRF51822 Test (3)

Test new nRF51822 breakout board and new J-Link downloder.

Apple ANCS with CC2540 (2)

1.Use iPhone 4s 6.x run LightBlue

2.Select 7905xxx UUID you will found 3 service UUID

3.Pict the 9FBxxx UUID , set start notify

4.You will get notify and its data when you received a new Email.

PS.I use sandeeomistry's code on my iPad Mini to Advertizing ANCS UUID as peripheral.

Apple ANCS with CC2540 (1)

之前的BLE Project都是把 iOS Device 當成Central BLE Device as Peripheral. 還蠻自然的. 可是當你要Access iOS Notification時 問題就來了

1. iOS 不提供Private Notification 就是說Email,SMS,Phone Call....你無法自程式中取得再丟給BLE Peripheral

 2.這些Notification 必需透過 Apple ANCS (Apple Notification Center Service)來取用

這時BLE Device的功能就要由Peripheral 轉成 Central 因為這時的 iOS Device把自己轉成 BLE Peripheral 透過BLE Notification來傳資料 （一切都為了省電）

這下子 CC2540又有事要做了！

iBeacon Scanner on iOS (3)

Test iBeacon's iOS Native Location Manager's Events. When App run in background LocationManager will send event about iBeacon Enter or Leave. The problem of this method is you can monitor only 20 locations and the response time is slow. When I turn on the beacon it show Enter in 20~30 seconds. When I turn off beacon it show Leave also in 20~30 seconds. I think there is no way to change this.

iBeacon Scanner on iOS (2)

Source code at Github

1.Add iBeaconState to monitor the status of iBeacon.

2.Add iBeaconAction to define action that depends on the status of iBeacon and BeacobID

iBeaconState : Enter/Leave/In/Out 

ToDo:Add another class to warp the beacon related operation.

ToDo:Local Notofication and Backgroud iBeacon Ranging

nRF51822 Test (2)

2013年12/31日最後的殘念 nRF51822居然連Download 都無法正常工作 搞了一整天還是不會動 元旦假期過後 上班第一天 拿來新的線馬上就會動了 可是還是覺得之前的現應該不會錯 所以又用舊的線再弄一次 接接 居然會Download Code了 完全不知道為何 ！（我想是因為Mac 重開機的關係 基本上用了Virtual Machine後PC當掉 也都沒有重新開Mac 因此我想是這樣吧）

CC2541 SI4703 Radio Control

1.I change the CC254x board to use 18650 Battery

2.Add Si-4703 FM Radio board control.via I2C

3.We can use iOS to select Channel , not so excited :(

4.Source code https://github.com/tzechienchu/CC254X

ToDo: Start iOS Side Programming. 

CC2540 GPS Parser

CC2540 nmea code parser. Only parse $GPRMC sentence. We can have BLE GPS for iPod Touch 5.

031904.00 is Time

2503.37923 is Longtitude

12135.57185 is Latitude

Source in Git (SerialApp.c)

CC2541 SPI Flash Memory Test

Anything intersting to add on ?

PS.CC2541 + Si4703 FM Radio = BLE Radio for iOS. (But Earphone company could build this into the earphone, so earphone can function as FM Radio control by Phone or normal earphone)

PS.CC2541 + GPRS so we can use iPod touch 5 to make phone call.

iBeacon + RTC

1.Change Broadcasting period in different time. Save Battery and improve resposive.

2.Change UUID in different Day as promotion.

3.Random change UUID in different Day as Saving Coupon.

CC2541 I2C IO Expander PCF8574

This one is simple.

CC2541 I2C OLED Display

Connect to I2C OLED Display 128x64. You can get this module from SeeedStudio 

I think I can build BLE control car , direct from CC2541 without Arduino.

ToDo: I2C Memory Access.

CC2541 I2C RTC using PCF8563

I don't know, why I need a RTC for BLE, maybe we can make a Clock that has BLE capability . Then we can use mobile phone to calibrate it. (Seems not very interesting).

I pick RTC is because that is the I2C device I have  that work under 3.3V

CC254x BLE UART (3)

I think, I can make every profile now. hahahaha.

This version is limit to send 16byte of data each time. No buffer control of the data from RX port.

ToDo:iBeacon Router via Raspberry Pi or full function iBeacon.

ToDo:OAD and myabe USB or I2C on CC254x

If you are interest in the source code, email me.

 

 

CC254x BLE UART (2)

Start from scratch, learn to play the simple peripheral profile. Add more byte to send out and more byte to read in. The I can put the data to UART. 

BLE Infrared Sensor as Traveler's Guard

CC254x BLE UART Bridge using Biscuit (via RedBear Lab) (1)

Try to port the RedBear Lab's CC2540 UART Bridge. But unsuccess. Using 1.2.1 Lib, the Serial Port unable to read data from UART. And using 1.3.x Lib, the board just keep boot up again and again. Still no cue about what happen. I think I have to move to study the simple profile and add up my own UART stuff.

I need to learn how to make my own profile .

CC254x BLE Broadcasting Ticks

 I like BLE's Broadcaster, it is simple. And simple is good. You can broadcast Temperature, Battery Level,Time,Humidity and ......

Most of the time, we just need Broadcaster. Not full feature BLE server.

Because of simple Broadcaster, we can build simple Observer.

ToDo:OAD or UART to BLE Bridge

CC2540 BLE Advertising Data Monitor (1)

I know I can use TI's packet sniffer to catch the data. But I think it is much fun to build a tool that can get the advertising data. This time I need the key to act as "Scan" "Up/Down" .

And it is  also a very good ble study.

ToDo:Add Key Control

iBeacon on Cruises

遊輪很大 因此可以用iBeacon來作為旅客在遊輪上的電子導遊

CC2540 as iBeacon Observer (5)

Source Code:

Download BLE-CC254x-1.3.2-simpleBLECentral_Keyfob.rar

Attention:

1.This project use different hal_lcd driver. If you use TI's SDK board, remember to use TI's original library.

2.My beacon's uuid is 0x5AFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF you can change the UUID in the code. 

3.I remove all Key operation. Eveything is done perioidcaly.

4.Command to set UUID

set 1st 8 word   UUID,01,5AFFFFFFFFFFFFFF

set 2nd 8 word UUID,02,FFFFFFFFFFFFFFFF

store 16 word uuid UUID,03

clear 16 word uuid UUID,00

ToDo: Study Broadcaster. (Like broadcasting Temperature .....)

CC2540 as iBeacon Observer (4)

Finally got UART right. I use UART to send/receive data.

ToDo:Change UUID from UART port.

CC2540 as iBeacon Observer (3)

Periodic Scan iBeacon and Show on LCD (6 seconds scan cycle)

ToDo: Set UUID through UART and output Beacon to UART.

CC2540 as iBeacon Observer (2)

Show RSSI and Minor Number !

ToDo : Setup UUID to monitor 

or Move to use RPi as iBeacon Router.

CC2540 as iBeacon Observer (1)

CC2540 scan the BLE Device and display the UUID (I think)

Next step is to access the UUID/Major/Minor Number of the iBeacon.

iBeacon for all Road Crossing

在十字路口裝設iBeacon這樣盲人就可以知道目前路口的紅綠燈情形

iBeacon for Patrol

在大樓個個樓層的特定位置 或是工廠的需要巡邏的地方裝上iBeacon 當警衛有巡邏經過那的地方時 巡邏警衛的iPhone 就會記錄時間和iBeacon的id 可以作為巡邏記錄 (Easy to deploy)

也可以倒過來做 每一位巡邏身上有一個iBeacon 然後特定的區域有一個 iBeacon的Logger 可以Log 誰經過了那些地方 然後再Upload to Server. (More cost effective and easy to extend)

BLE as Universal Remote Control

BLE 很便宜約 < 2USD , 如果目前所有的電扇 冷氣 電視 音響 都改用BLE 那麼我們就可以使用iPhone or Android Phone 來控制家電了 超大的市場！

iBeacon Router

如果用使用iBeacon在室內定位移動的人物 就需要iBeacon Router 就是專門收iBeacon 資料然後放到Server上的機器

iBeacon in Hospital

如果iBeacon的頻寬可以在醫院使用的話

1.iBeacon可以用來標示地點 因為醫院實在容易迷路

2.iBeacon可以用來標是患者是不是在現場 

iBeacon for Taxi Identification

假設每一台計程車都有裝iBeacon 當乘客上車APP就會根據iBeacon的ID 由Cloud找到計程車的資料 Log下來你的上車時間與地點 with 計程車的資料

當然也可以當成一種安全標章 有iBeacon代表有認證有資料的 攔車時也可以馬上知道沒有iBeacon就不上去了

iBeacon(BLE) for Restaurant Wait List

在台灣一些熱門的餐廳都有排隊等候的情形 基本上就是人工登記 人工叫號 其實使用iBeacon 就可以不必大叫 因為你知道客人在哪邊 因為Beacon 無法收訊號 因此如果是用BLE的形式 就可以通知Beacon的持有者可以進入餐廳了 當然啦還是不能走太遠 

其實也可以單單使用iPhone 將iPhone變成一個Beacon就可以了

iBeacon as CoolCard Stand

記得很久以前有一種廣告叫做"酷卡" 不知道現在還有沒有 反正就是一個柱子上面放了很多明信片大小的廣告 有些設計的很不錯 有些就只是照片沒啥意思 總之就是把酷卡虛擬化 特定的地點特定的時間 你經過那邊並且你裝了酷卡APP 你就會收到限量的設計數位酷卡 幹嘛呢 當然還是廣告 哈哈啊

iBeacon for Wall/Stand/Board Shopping

我們有Window Shopping,有Web Shopping 我來推一個Wall Shopping. 什麼意思呢？就是在牆上貼上你要廣告的東西加上iBeacon 之後呢 有裝WallShopping App 的人經過那片廣告牆/看板/公車亭時 就會跳出來教你購買的頁面 你馬上就可以購買 或許頁面上還有價格的變化與購買的人數之類的 總之走到哪買到哪！
