Issue using Bluetooth devices

[iz0zpb]

Hi all, I have a problem when using a Bluetooth device for audio in TX and RX. The Bluetooth device I am using is a TSA6015 (the one in the photo), the smartphone is a Motorola Moto G84 (I tried even with a rooted Asus ZENFONE MAX PRO M1-X00td), I'm using FT8CN v0.92. If I configure this device to handle both calls and multimedia audio (through Android settings), FT8CN decodes the audio, but when it goes into TX, it does not send the audio to the Bluetooth device but to the smartphone (this should be the correct Bluetooth configuration); if I configure the TSA6015 (still through Android settings) to handle only multimedia audio, it works well in TX, but not in RX as FT8CN takes the audio from the phone and not from Bluetooth; if I configure the TSA6015 (again with Android settings) to handle only calls, reception works well, but in transmission, it sends the audio to the smartphone instead of to the Bluetooth. FT8CN always shows the message "enter Bluetooth headset mode". I just tested that the same problem occurs with Bluetooth earphones. How can I solve this? Thanks in advance for the suggestions
