Have you changed the uuid's of the projects? notif_enable() is only called if the correct service is found during service discovery. Can you add some prints to see if notif_enable() is called, and also the results of the service discovery (inside db_discovery_evt_handler in client_handling.c.

Which SDK are you using? If you have modified the example a lot, please attach it here

Thank you for your input. Well since the example is already configured to enable notifications in the notify_enable() function, I would assume that this was working already?

Since the system works when you are connecting to MCP, the problem is probably that your client code does not enable notifications on the characteristic. The server cannot send notifications before this happens.

BLE_GAP_EVT_SEC_REQUEST

I checked the header ID's on the ble events that comes in on the client:

0x10 : Connected
0x1A: RSSI change
0x1A: RSSI change
0x30: Primary service descriptor read
0x32: Characteristic descriptor read
0x33: Descriptor read
0x37: GATTC evt write
0x18: Connection security update
0x11: Disconnected.

After that it continues to connect and disconnect.

I also get a header id 27 ( 0x1B) but I cant find what that means? Anyone?

From what I can see the BLE_GATTC_EVT_HVX event never arrives. What could cause this? The notifications pops up on the master control app?
