Oristo,
All Vaclav needs to do is use one of the unused serial ports on the chip and use a BT to serial module.
I was looking at the F072 specs and it appears the serial pin I was thinking if using is also used as an SPI line (are there SPI to BT modules?)
Can one of the STLink lines at the edge of the PCB be reprogrammed for serial?

Hi Vaclav -
I am planning to add Bluetooth USB dongle ( hardware) to MY NanoVNA, including
necessary software.
Unless you find a Bluetooth dongle that supports USB OTG, I think that this is doomed.
I found no 64-pin STM32 chip, as in nanoVNAs, that does USB OTG,
/g/nanovna-users/message/5373...resulting in a classic "failure to communicate".
