what's the meaning of error no. NRF_ERROR_BUSY

[Ricky]

When I use sd_ble_gap_adv_start( ), sometimes get return value NRF_ERROR_BUSY . What's the meaning of this error No. ?

Maybe you trying to call sd_ble_gap_adv_start() when you already advertising and get this error?

thank you! I add softdevice_ble_evt_handler_set() in my code, and never set advertising_state = true, then the board never reboot.In another words, this code do nothing but the board works good. but if I set advertising_state = true when advertise start, the board will die as before...so puzzing...I will try to find why
