Steps

1. Power on board and select bluetooth workflow.
2. create new connection or reconnect NOTE "Bond" button never enables
3. editor opens with blank document, but will not save
4. Trying to use open button also hangs with spinner

I'm pretty sure the actual error is in https://github.com/adafruit/ble-file-transfer-js. It could be something like the BLE connection was disrupted and that lib isn't handling it very well.

[wuftymerguftyguff]

Are you able to recreate the problem? Or does the BLE workflow work for you?

[makermelissa]

I haven't actually started working on this problem yet. I am working on fixing some more generalized bugs and revamping some of the file transfer stuff. BLE probably needs some work done and is the most frustrating workflow in my experience. In the meantime, you can check out this troubleshooting section: https://learn.adafruit.com/wirelessly-code-your-bluetooth-device-with-circuitpython/device-setup#troubleshooting-connection-issues-3106121. The guide is getting a little old, but hopefuly still helpful.

[wuftymerguftyguff]

I have followed the guides you mention with no real joy.

I have a thread in the forum too

Ok, I was working with BT Workflow last week and it definitely needs better error handling (i.e. returning control to user and displaying what happened).
