I have some questions about connection Q64 Wireless Processor to PC via UART.
I’ve made connection according to the circuit below.
Module is turn on (the led lights), and then I send the “AT” command to Q64 with HyperTerminal. But there isn’t any answer from Q64.Could I use MAX232 ? Might be something special in Q64 UART connection circuit ? Is my circuit correct ? Is it important to use CTS/RTS pins?
Thank you for some advice!
