I am amateur for GATT and ble.

I am using Linkit one board as central device and Nrf51 board as peripheral device. Central device successfully connecting with peripheral device, able to seach all Services UUID, Characteristic UUID, but it fails to read the characteristic value. Value which display on Linkit side it is not same as mentioned in nordic side.

I am able to get the characteristic value in nordic app and as well as nordic board as an peripheral device.

Linkitone as central device fails to read TX characteristic value of nordic uart service from any peripheral device. Even when I tried Linkitone as peripheral device and try to read the Nordic uart service value by nordic app, it fails. App get hanged every time.

Below I mentioned the value which gave to tx characteristic the value which is getting on central side. So is there any problem with Linkitone board with ble UART service or there is any different reason for this?

  • Is it a read response we see inside the red circle or a notification? – Emil Nov 22 '17 at 19:12
  • this read response. – suvarna Dec 06 '17 at 07:09
  • I am able to solve this problem. One step I was missing after enabling notification, descriptor should be set and then Device is successfully getting tx characteristic value. – suvarna Dec 06 '17 at 07:12
