Firmware-Update with OSTC not possible

[Dirk Lehmann]

Currently I cannot do Firmware-Updates with my OSTC2.
Problem is, that connection has to be Bluetooth-Classis to be established. BLE ist refused.
But with BT-Classic-connection, as soon as I have chosen the firmware-file, the connection is ended immediately, but no firmware has been transferred. 

When I change the Settings of the OSTC2 (Only changed the text) I get an error message "Data RX Timeout" - but the data seems to be transferred.

Any ideas how to transmit the firmware?

I do mine with the OSTConf smartphone app.

What version of Subsurface are you using, and on which operating system?

From which version to which version are you trying to upgrade your OSTC2?

I did a firmware upgrade on an OSTC plus (same firmware as OSTC2) to
3.34 with Subsurface a couple of weeks ago, and this went smoothly.

But yes, OSTC2 seems to be having a problem with Subsurface when using
BLE at the moment.
