Troubleshooting connection issues with the Updater

If the web updater fails to connect, you may need to use a pair of metal tweezers, for example, to short 2 points on the board before connecting.

1. The symptom is the failure to connect to the Bluetooth module with the error below

2. The part C10 needs to be shorted by a pair of metal tweezers or anything metal.

3. While the points are being shorted, click on Connect in the updater and the connection should be successful.
