I sould get some date from uart serial with .read() or readline() functions, but theses functions only get some chars after about 100.
So, the func serial has the param rxsize and txsize, however these value are 0, 256,512… I connect the device who’s send 12 HEX varieble, but 4zerobox dons’t recive each HEX. It’s recive 120 HEX.
How can I fix this? I want to recive each HEX separately.
