Hi,
When pointer the p_conn_params of ble_conn_params_init_t to NULL for ble_comm_params_init(), the connection will be disconnected fast automatically, test with the heart rate demo of nRF-toolbox app.
- If pointer the p_conn_params to a conn_params, the connection will work well.
- or, If pointer to NULL and test with TI multitool app, the connection will work well.
How about the issue?
Test with:
- SD v7.1
- Android 4.4 and iOS 8.x
- latest nRF-Toolbox app.
