Hello,
I have installed a HC-05 bluetooth module in my NanoVNA-H4 (board v4.2). Since connection pad P3 says UART_TX and UART_RX I connected the TX and RX from HC-05 that way. I can not get any connection, I tried to reverse RX and TX but that did not help, and should not. I am using Dislords FW version 1.0.64 and I set Connection to Serial and Serial Speed to 38400 (also tried other speeds with corresponding change for the COM-port). I have connected the HC-05 in my Win10 PC and initialized an outgoing COM-port (HC-05 SPP Dev). I set the speed for the COM-port to 38400. No function. I have also tried Windows original installation which gives two COM-ports, out and in, and used the out-port (also tried the other but that would be wrong). The HC-05 flashes red as it should. What happens in NanoVNA App is that it shows connected briefly then disconnected. Using Tera Term VT and setting the out com-port and serial speed 38400 gives a terminal window that does not accept any input, some letters are accepted but I can not type a complete console command (as I can with USB-cable connection), some letters are displayed as figures. I have tried to disable the FIFO-buffer for the COM-port, but that does not help. Now I have run out of ideas so any help would be gratefully received. I know that some of you have succeeded. I have followed the previous thread on the same subject to no avail.
