I am trying to upgrade the firmware version FW 06.57-A07.03 for sara-N280-02B-00 NB-IoT module and I am using the Genuino Zero (32 bits Arduino board) with the NB-IoT shield.
First I loaded the following passthrough sketch on the board then I opened UEUpdaterUI v3.17.0.13 on my computer to perform the update but It is stuck in “Trying to reset UE using AT command”. What am I doing wrong ?

unsigned long baud = 9600; //start at 9600 allow the USB port to change the Baudrate
void setup()
{
// Turn the nb-iot module on
pinMode(powerPin, OUTPUT);
digitalWrite(powerPin, HIGH);
// Start communication
USB.begin(baud);
UBLOX.begin(baud);
}
// Forward every message to the other serial
void loop()
{
while (USB.available())
{
uint8_t c = USB.read();
UBLOX.write©;
}
while (UBLOX.available())
{
USB.write(UBLOX.read());
}
// check if the USB virtual serial wants a new baud rate
if (USB.baud() != baud) {
baud = USB.baud();
UBLOX.begin(baud);
}
