We want the system to be in low power mode in idle state. Therefore after advertisement is sent the BLE is switched off using bt_disable. The return for this function is fine. But after sleep
when we try to enable ble using bt_enable, this function returns -11.
We debugged and we saw that the end point attach does not happen and so the semaphore take function() fails.
Can you tell us what we are missing. We are attaching the prj.conf file of application core here.
We are using nrf sdk version 2.,6.1.
it fails at k_sem_take(&ipc_bound_sem,IPC_BOUND_TIMEOUT_IN_MS); it returns -11;
