ttyS0 & ttyS1 - J9 & J7

[Mladen Dryankov]

Hi folks,

So far we use J7 (pins 11&13). Now we need to connect second device for communication (obviously on J9). 

I saw J9 pins 11&13 are used for back and menu buttons as well. Should I disable them (bypass them) somehow? And if yes - How?

Thanks in advance for your effort.

Best regards

Mladen
