Sanwu HF-183 Programming Question

[6L6MAN]

Hello all, I would like to access the BT module on a HF-183 unit. Does anyone know if the usb port on the board can be used for this? I've read a lot of how to guides regarding soldering pigtails on other boards and using a converter/programming module but I've never found anything on this particular one that has a usb port. Thanks

J7 function: This is a reserved hole for development and has no other functions.

So this port must be the one for programming. But i dont know how. I want to hack it too to edit EQ and name of BT.
