Model and file transfer via BT not working

[lthole]

1.5.7 pre-release, using X20 and X20 Pro

I have been unable to transfer models between the 2 radios. I have tried in the ‘Receive model’ function under Model Select, and also using File Manager. In case it was my models (which have been up-converted many times) I also created very simple models which also fail. I get an error at the end of the progress bar.

I have tried in both directions.

From My side 1.5.7 pre release - X20S Vs X20HD everything works.... in both directions

I also noticed that if the process does not complete, it does not re-initialize properly. It tries to continue with the initial attempt even if you switch from receiving at one end to sending.

@lthole are we sure that the transfer fails, or could be it that the conversion fails (from X20 to X20-PRO)

Test 1: From X20 Pro to X20, simple file BTtest3.bin attached.

Screenshot 1: X20 goes into waiting mode:

Screenshot 2: Pro tries to send

Screenshot 3: X20 responds

Screenshot 4: Transfer failed

Test 2: from X20 to Pro

Screenshot 1: Pro waiting for file

Screenshot 2: X20 trying to send, but no response

Test 3: After X20 failed to send file to the Pro above, I put X20 into 'Receive model' mode, and it immediately thought it was about to receive the model I had just tried to send to the Pro. Looks like it didn't re-initialize when I changed from Send model to Receive model.
