Hey Nordic,
My project is based on "ble_app_uart" and "ble_app_uart_c" examples. I modified them to some extent. You can download them from here.
Normally, I can write some values into any characteristic of my custom service as shown above in nRF Connect. But I want to do the same thing automatically with my central device to the peripheral one. I want the central to discover this custom service, and write some predefined value into a characteristic specified by a UUID.
I tried to log the discovered characteristics in db_disc_handler() function but it seems that it can only discover or log the characteristics of the NUS service to J-Link RTT Viewer as shown below:
00> <info> app_timer: RTC: initialized. 00> 00> <info> app: BLE UART central example started. 00> 00> <info> app: Connecting to target 7F0F251956F2 00> 00> <info> app: ATT MTU exchange completed. 00> 00> <info> app: Ble NUS max data length set to 0xF4(244) 00> 00> <info> app: Discovery complete. 00> 00> <info> app: Connected to device with Nordic UART Service. 00> 00> <info> app: srv_uuid.uuid: 0x1 00> 00> <info> app: srv_uuid.type: 2 00> 00> <info> app: char_count: 2 00> 00> <info> app: chars[0].char.uuid.uuid: 0x2 00> 00> <info> app: chars[1].char.uuid.uuid: 0x3
So, how can I discover my custom service and write some value into a specific-UUID characteristic of the peripheral device using my central device?
Thanks,
Omer
