Hi,
is anyone able to connect the ESP8266 to the TIAO Tumpa module?
All I'm able to get from the modules is garbage on the terminal, no input command is working either (which would look like wrong connection parameters ...)
I tried all bandwidth speeds between 9600 - 115200 without success.
I already ordered some level shifters in order to be able to use another rs232 -> serial adapter to be sure that the Tumpa itself is not the problem..
