Latest Sony Phone with accessible UART Port?
since your open devices provide (at least some of them) an accessible UART port.
Is it only the RX part of the connection or would i be able to interact with the system?
If yes, what is the latest Sony device with >= android 11 and accessible UART port?
I would like to use the UART for KGDB
Thanks for your replies,
