Hi

The error code 0x11 points towards the SoftDevice being busy, which means that the SoftDevice is busy doing something else when you're calling the ble_db_discovery_start() function. From your log, it seems like you're doing this while the device is trying to connect to a peripheral. Please try calling this once the device has connected successfully to the peripheral device.

Best regards,

Simon
