Hi! I have a question. For communicating with TELIT i’m using only 3 lines RXD, TXD and GND.I wrote a small script in Python and i would like to download it to module. So my question is: Do i have to use hardware flow control to download it and also use the pins CTS, RTS?
Flow control should be used if possible. The RTS / CTS lines can be tied if required.
