I've used the Tessel board for more than 1 year for IoT Demo development.
Recently, the board suddenly stopped working. I'm not sure if the board is damaged electronically or not. Since the board keeps booting forever so I cannot use t2-cli to get further information.
Here's the event when it stops working:
- I'm connecting the board 2 modules: Ambient & Climate.
- I check the data sent from the board; I found that there's no data for Ambient.
- I checked & found that the Ambient is loosely connected with Tessel 2 board. So I reconnect them.
- After that, the board (seem to reboot) keep blinking the Blue LED forever.
I tried to remove the cables, try again with mutilple power source but the same issue.
Do you know any reason could be?
How can we reset to factory setting (using hard button)?
(since t2-cli cannot be used)
Thanks a lot,
