SensorTile.BOX sudden failure [Copy link]

 

For various reasons, I haven't used this for a long time...

But once connected, this problem will easily occur

But from the notification bar, you can see that it is connected normally.

Originally... it was fine, I could connect normally occasionally, and then... this morning, I couldn't connect (I couldn't search it directly), the charging light didn't come on, but the C152 was hot, and the main control chip was slightly hot... Is this my problem?

Check if there is any short circuit and whether the system voltage is normal.

After recovery, long press PWR once, short press twice, USR green light flashes twice, then it can be detected, but the problem of not being able to connect still exists (the second picture..)

Try updating the firmware and deleting the Bluetooth device on your phone and reconnecting. This usually works in other apps, but I don't know if it works for SensorTile.

It seems that the main controller is good. Disconnect the battery and try using USB power supply.

Thank you, moderator. I checked it again and it turned out to be my data cable. The board itself is fine. Now it's just a problem of unstable connection.

"Press and hold PWR, press and hold twice, and the green light on USR will flash twice." Where did you see this operation?

Firmware problems can be upgraded using the APP, or reflashed using USB DFU mode.

Where did you learn this method?

Long press PWR once, short press twice, and the green light of USR flashes twice.

Sometimes when you press other keys, the green light flashes twice.
