NRF52 NRF_ERROR_BUSY when calling ble_db_discovery_start()

[Sergy]

Hi, I have nrf52 setup as central and peripheral.

As central it connects to another peripheral and everything works just fine. After it did connect I turn of peripheral and when I turn it on again NRF52 connects to it, but then I get NRF_ERROR_BUSY when calling ble_db_discovery_start Here is the log that leads to the error:

 0> APP:DEBUG:ble_db_discovery_on_ble_evt, evt_id=17
 0> APP:DEBUG:on_ble_central_evt
 0> APP:INFO:LBS central link 0x1 disconnected (reason: 8)
 0> APP:INFO:link 0x1 established, start discovery on it

Seems like its still discovering old connection or something like that? Any idea?

Thanks!

If you see inside ble_db_discovery_start(), is it returned because of discovery_in_progress being true? If it is, are you sure you are not called ble_db_discovery start() somewhere else? If not, could you check the status of discovery_in_progress before you connect the second time?
