FAQ for the Arduino MKR NB 1500

Hi there,

If you've got a question on the Arduino MKR NB 1500, which is related to the Connected Things API, check out our FAQ first; https://dev.telstra.com/support/frequently-asked-questions , or join the community with our good friends at Arduino; https://forum.arduino.cc/index.php?board=107.0.

thanks,

Firmware upgrade of the UBLOX SARA-R410M-02B on the MKR NB 1500
Hi David, We're building an MVP agricultural focused product around the MKR NB 1500 and need to upgrade the board's UBLOX SARA-R410M-02B firmware for some additional power saving functionality. However we cannot find any documentation on how the access teh UBLOX SARA-R410M-02B in order to perform and upgrade. We see some solder pads on the board which might be a spot for a connector but need clarrification. We are also a little confused as to whether the current Ublox firmware that ships with the board actually supports Cat-NB1, from what we can see it only supports Cat-M1 at present; is this correct? More information from Ublox here: https://www.u-blox.com/sites/default/files/SARA-R410M-02B-01_PCN_%28UBX-19024506%29.pdf Regards Mark

NEXT STEPS: Firmware upgrade of the UBLOX SARA

Hi mark_5sorry for the delay on this one.

Can you please provide us an update on where you got to? Hope your IoT agri-prototype was a success and we’d love to hear about it!

I have confirmed that the device with original firmware will work with a NB-IoT enabled SIM, however the SIM included in our Arduino kit is Cat-M1 only. To access the NB-IoT network on this device, please reach out to the team at telstradev@team.telstra.com

 

As for upgrading the firmware, this is a bit more complicated. Check out this link  which contains documentation about the SARA-R4 series. Just to add, this file could also provide more information regarding the firmware upgrade. On the said doc, in section 1.6, there appear 2 options for updating the firmware.

For the firmware update procedure, I ask you contact u-blox support directly. We actually reached out to u-blox support to check on your enquiry, and they informed us that firmware is considered confidential and required NDA for delivery. You can create a support ticket with ublox on this page, but before you can raise a ticket registration is required. Please use this link to register.

I see you've also reached out in the arduino forums, If you found your answer there please share with us here for next time!

Hope these items help. If you have any questions, please let me know! 

Cheers,
Michelle
