Wio LTE Cat M1/NB-IoT RSSI example not working

Post by yangdavid1028 » Tue Dec 04, 2018 2:24 am

I configured the system and the Arduino IDE as instructed. Then I ran the default RSSI reporting example of the Wio LTE Cat M1/NB-IoT board. However, the board keeps outputing "." at the serial port. In other words, the SARA module is not alive.

Do you have any suggestion?

Thanks.

MAKE A BACKUP FIRST!
Then in ublox_sara_r4.cpp (in library src) try changing PowerOn() to:

void Ublox_sara_r4::powerOn(void)
{
init_AtTransport();

// Enable power to the module
pinMode(MODULE_PWR_PIN, OUTPUT);
digitalWrite(MODULE_PWR_PIN, HIGH);

// Pause a bit to allow power to come up
delay(100);

// Assert PowerKey pin for just over 3.2 seconds
pinMode(PWR_KEY_PIN, OUTPUT);
digitalWrite(PWR_KEY_PIN, HIGH);
delay(3500);
digitalWrite(PWR_KEY_PIN, LOW);

// Pause at short while
delay(200);

// Assert it again for just under a second
digitalWrite(PWR_KEY_PIN, HIGH);
delay(800);
digitalWrite(PWR_KEY_PIN, LOW);

// Set RTS pin low to enable UART communication
pinMode(RTS_PIN, OUTPUT);
digitalWrite(RTS_PIN, LOW);
}
