E54 — BLE_BONDABLE_FAILED

Setting the BLE connection's bondable mode failed.

What happens​

The current connection attempt is abandoned (continue 'outer) and the device retries the connection loop immediately. The error is recorded once per boot.

Possible causes​

  • The BLE stack rejected the bondable flag, possibly because the connection state changed between being established and this call.
  • A transient stack state issue.

How to fix​

  1. Wait — The outer connection loop retries automatically.
  2. Reboot the device — Resets all BLE state.
  3. Contact support — Open an issue on GitHub if this recurs consistently.
