Description
Hi ,
I am trying to connect my Lora module with ESP32-c6 over UART Rx Tx line. UART 4,5 are already used in connection with GSM Module. I am trying to use ESP32-c6 UART Pin N.o. 16,17 with Lora Module , but Rx is not receiving the packets as GPIO17 is default function active. How to enable the Rx function in Arduino IDE?
As checked in c6 documentation, there are 3 functions associated with GPIO 17.
1.)Rx
2.)GPIO17
3.)Chipselect.
By default f1 is enabled. We need to change the function to f0. tried below code but it didnot work out.
#define IO_MUX_GPIO17_MCU_SEL 0;
Same piece of code is working when i am using UART Pin# 4, 5.
I am quite stuck due to this issue in prototype phase and would really appreciate your support here.

void setup() {
Serial.begin(9600);
Serial.println("In setup mode");
delay(500);
// Startup all pins and UART
e32ttl1w.begin();
nodeConfig();
}
void loop() {
if (e32ttl1w.available() > 0) {
Serial.println("———-");
rc = e32ttl1w.receiveMessageUntil();
if (rc.status.code != 1) {
rc.status.getResponseDescription();
} else {
// Print the data received
Serial.println(rc.data);
}
}
delay(100);
}
void nodeConfig() {
ResponseStructContainer c;
c = e32ttl1w.getConfiguration();
Configuration configuration = *(Configuration*) c.data;
configuration.ADDH = 0x0;

configuration.OPTION.wirelessWakeupTime = WAKE_UP_1250;
// Set configuration changed and set to not hold the configuration
c.close();
Serial.println("Updtaed config is ");
ResponseStatus rs = e32ttl1w.setConfiguration(configuration, WRITE_CFG_PWR_DWN_SAVE);
Serial.print("Config: ");
Serial.println(rs.getResponseDescription());
