@gksrb4, I'm not able to reproduce the issue you are getting. Could you describe more what files you are using for the connectivity and the peer device?
Also, there was an update of ble-driver in latest nRF Connect for Desktop which could be relevant for this issue. Could you see if you get the same error with the latest version?
