Hello
I have tried to communicate wit IoT da14583 sensor (https://support.dialog-semiconductor.com/connectivity/reference-design/d...)用蓝牙耳机扔笔记本。在这个笔记本上安装了Ubuntu系统。
我在用pygatt(https://github.com/peplin/pygatt) python3 library for communication.
My sequence for communicate is:
adapter.connect('80:EA:CA:00:D2:9D')
-- is connected successfully
-- i could read device name with uuid 00002a00-0000-1000-8000-00805f9b34fb
subscribe('2ea78970-7d44-44bb-b097-26183f40240a',callback = commandReply) #set callback function for command reply
char_write("2ea78970-7d44-44bb-b097-26183f402409", bytearray([0x0B])) #send into controlPoint 0x0B - automatic
字符写入（“2ea78970-7d44-44bb-b097-26183f402409”，bytearray（[0x01]）发送到我准备好的控制点
subscribe（'2ea78970-7d44-44bb-b097-26183f402401'，callback=accelerator）#设置加速计数据的回调函数
Everything is ok but data is not received.
Am I doing this uuid sequence right?
谢谢你迈克

Hi missinik,
In order for the device to start sending data you should enable the device to start notify your central for the characteristics that you would like to be notified, there is a series of commands that should be send and the notifications should be enabled as well from the central, please check the UM-B-063-DA14583_IoT_Sensor_Development_Kit.pdf for the available characteristics and control point that the application implements.
Thanks MT_dialog
谢谢你的回答。
Actualy I have already red the document which you wrote about (it is capture 6).
我的顺序是:
1. subscribe control reply characteristics ....240A
2. write command 0x0B (to load configuration) into control char.
3. write command 0x01 (start command) into control char.
4. subscribe accelerometer data chaacteristics ....2401
after that i think that data should be send, but nothing happend.
Finally it was a bug in bluez (official bluetooth lib. in Ubuntu) and that sequence as I wrote is right!
谢谢你迈克
ps: Also I have created wrapper for controlling Dialog IoT via linux distribution and BLE.https://github.com/misisnik/FoshWrapperHope it could be helpfull for someone...
Hi misisnik,
