In case you need to know the firmware version of the u-blox SARA radio module of your MKR NB 1500, here is how to find it:

Using the Arduino Desktop IDE

1. Ensure that the MKRNB library is installed in the Library Manager (Tools > Manage libraries).

   

2. Select the Arduino MKR NB 1500 as the Board (Tools > Board: > Arduino SAMD (32-bits ARM Cortex-M0+) Boards > Arduino MKR NB 1500) and its corresponding Port in (Tools > Port).

3. Open the SerialSARAPassthrough in File > Examples > MKRNB, under Examples from Custom Libraries.

   

4. Open serial monitor

5. Set serial monitor dropdown to ‘Both NL & CR’

6. Use AT commands ATI9 or AT+CGMR and press ENTER

   • ATI9: returns the modem firmware version and the application version of the module:

     

   • AT+CGMR: returns the firmware version of the module together with its release date reported within square brackets:

     

Using the Arduino Web Editor

1. Click on Libraries and type "MKRNB" in the search box

   

2. In the MKRNB Library click on Examples > Tools > SerialSARAPassthrough

   

3. Upload ‘SerialSARAPassthrough’ sketch

4. Open serial monitor

5. Set serial monitor dropdown to ‘Both NL & CR’

6. Use AT commands ATI9 or AT+CGMR and press SEND

   • ATI9: returns the modem firmware version and the application version of the module:

     

   • AT+CGMR: returns the firmware version of the module together with its release date reported within square brackets:
