Hi bergmanu, i use the UART method of Mraa class in eclipse to finish the com communication . But i found some problems (the pico i used is the release one not the sample) : 1. when i use the writeStr method , the receive port will receive the string but have "!!" characters in the front of it. If i did not use writeStr method ,it also receive the "!!" character. why ? 2. when i use the ReadStr method to get the string from send port , i found if the speed is not as fast as possible it won't receive any string or only a part of string or some wrong string. why ? Does it need the special com cable , i use the siemens box or panel com port cable? Best regards,
