"Write to BLE failed" on ESPDevice.scanNetworks

[QuentinFarizon]

Sometimes, randomly, I'm getting "Write to BLE failed" error in the onFailure callback of scanNetworks. From there, I always got this error when retrying to call scanNetworks.

Hi @QuentinFarizon ,

Please try again after disabling CONFIG_WIFI_PROV_BLE_FORCE_ENCRYPTION, which you can find under Component Config -> Wi-Fi Provisioning Manager.
