Radio telemetry kit no connect with pix 3 PRO:

https://drotek.com/shop/en/rf/795-radio-telemetry-kit-433-915-mhz.html

The green led is solid and red led flash = conection OK

But is not possible link with qground, i have tested with COM7:

COM7 is correct port assigned by telemetry:

Also de Sikradio software no load settings with COM7:

and with COM1:

nobody answers me?

Can you make sure no other program is trying to access the COM port? It looks like the port is busy is used by another process.

Problem solved Kevin.
