Currently I am working on BLE Master project using BLE1212LR. In this I am adding TIs keyfob slave device to my BLE Master. I achieved simple keys service. But I am not getting how to use the Battery service. In keyfob document and its BTOOL, they are showing that I should read the battery value by using "Read using characteristic UUID". Through their BTOOL software and dongle I am successfully reading the battery percentage. But I am not getting how to do "Read using characteristic UUID" through BGScript.
Battery service UUID is 0x180F
Battery level characteristic UUID is 0x2A19 and its handler value is 0x2F.
And I want to know in which event it will be good to read the battery percentage, like connection event or procedure completed event. Right now I want read battery percentage every one second so, I will read in timer interrupt event. But I want to read it like whenever I send some command through UART. So, in which event I should read and how to read.
By the way, I tried "attclient_read_by_handle" , but I am not getting any value from "attclient_attribute_value".
Please provide me example codes if possible.
Thanks in advance.
The BGScript function attclient_read_by_handle together with event attclient_attribute_value are correct for this purpose. Are you sure that you give the correct parameters? Could you please provide us your BGScript file?
Thank you so much for the help Mr. Bartosz.
For reading the battery Percentage, I tried with ReadByType function and it is working fine now. And i want to implement accelerometer service also in this code.
For this I need to enable accelerometer by writing 0x0001 to handler 0x0034 and to get notifications of x-axis changes, I need to write 0x0001 to handler 0x3B.
I am writing those but still I am not getting the accelerometer values from attclient_attribute_value.
I wrote the code for accelerometer same as I wrote for simple keys which is working fine.
Please find the attached files for code and details of the Keyfob.
One more thing I want to know is how to check the result of the function attclient_attribute_write.
