thanks for your answer, but the module use the uart2 ports and this works fine. my problem is to use the uart3 ports.

I stumbled upon this earlier this week when looking up the NEW GPIO app/function for my Raspberry Pi collection…it may help enable the uart3 for you. I don’t have a M3.

I test the uart port on BPI-M2+, and I think it will work well on BPI-M3. Please see this page https://bananapi.gitbooks.io/bpi-m2-/content/en/bpi-m2+uart.html
