Hi! I am working on a project that uses the Multilink example. On the client (nRF51422 w. SD 120) my program crashes and starts the main loop again after a few seconds. I have narrowed it down to in the client_handling.c file in the client_handling_ble_evt_handler().
The p_ble_evt->header.evt_id is 27. Then of course none of the cases is entered. What is causing this?
The problem has occured after I changed my server to send data with sd_ble_gatts_hvx() instead of sd_ble_gatts_value_set(), to preserve battery life. But with the nRF Master app the server data transfer and notification seems to work just fine.
Any suggestions?
Thanks!
