device does enter OTA mode

[universam1]

This problem appears with v1.8 trying to upgrade to v1.9. The device is reconnected but not entering into OTA mode.
Appears on THB1 and BTH01 devices I have.

Any idea?

[pvvx]

OTA works only through Boot.
(Options for switching in Boot are specified in the README.)
Disconnect the battery. Press the button and connect the battery.

[universam1]

What's the purpose of this button "Mode OTA" then?

[universam1]

I realize, this button does not restart into OTA mode, unless I press Disconnect manually which causes the device to reboot. Weird

[pvvx]

Based on your descriptions, it is not known why switching to Boot on command does not work.
There may have been failures in the Boot firmware or Boot from another version of the thermometer.
Therefore, try switching using the button on the thermometer and turning the battery on and off.

If this doesn't work, you'll have to reprogram it using a USB-COM adapter.
