I have a Wiz lora 100 device, I’m trying to interface w7500 with it so that I can send sensor data as well as AT commands from w7500, The issue I’m facing is that
1)The device is not displayed in my com port and I get Serial port COM 28 opening error any help as to why this happens.
- When I try to send AT commands from w7500 the reply I get is T and R characters, and not OK… Am I doing something wrong…
Serial pc(USBTX, USBRX);
Serial a (D1,D0);
c = ip.read();
// char data=‘h’;
pc.printf(“PIR Value : %d\r\n”,c);
