Hello,
using VictronConnect v5.49 app on Android, it is not possible to upgrade firmware on Smart Charger IP67, it fails always with
X88 - Kommunikationsfehler. Vreg ACK Zeitüberschreitung
The update stucks always between 5 and 50%. Currently installed version on the Charger is shown as "none".
Hi
What you can try is to remove the pairing in the Android Bluetooth menu: https://ve3.nl/VictronConnect_Bluetooth%20Smart-Removing-from-the-list-of-paired-devices
Is the phone also connected to some other Bluetooth device like a headset, speaker or smart watch? If so, could you please also try with that device disconnected/turned off.
Kind regards,
Thiemo van Engelen
