Device disconnects while writing to control point characteristics of cycling power service.

[bmaltim]

Hi,

We are developing the cycle power services and facing the issues in using the control point characteristic. I am able to connect and observe all the characteristics in the 'nRF_connect' . But when tried to write the control point characteristics to request the procedure, it gets disconnected. The 'nRF_logger' reports...

[server] Device disconnected

Error 133 (0x85): GATT ERROR

Error 22 (0x16):  GATT CONN TERMINATE LOCAL HOST

Disconnected

We are using Soft Device S332 with sdk version 15.3.0 on nRF52-DK.

How can we solve the issue?

Regards,

Malti

Hi Kenneth,

I have downloaded the 'nrf_sniffer_for_bluetooth_le_3.0.0.zip' file and gone through the documentation. If i understand correctly, one needs to run the sniffer code (sniffer_pca10040.hex) on sniffer node and place it between the two devices that are communicating to start recording the log in wireshark.

I could not get the sniffer log as i have only one nRF52-DK board. could you please do the needful. 

Thanks and Regards,

Malti
