I am trying since some time with an Up2Stream pro v3. I love this device, and since yesterday i am playing with the UART-commands.
I can receive the commands which the V3 sends very well, like when it is booting, changing the source by button or in NET-mode sending the track information.
But unfortunately i cand send commands to the V3.
I am using a small CP2102 USB-UART converter connected to the RX/TX-pins of the V3. Receiving works well. When i connect RX and TX of the CP2102 i can see what i write in the command line (PuTTY).
But when i write commmands like STA; or VER; or even SRC:BT; nothing happens.
Configs in Putty are 115200baud,8,N,1, no flow control.
Can you please help me or give me some clues where i made my mistake?
Best greetings and 73,
