XM122 XB122 prototyping

[AndreasLiebenberg]

Hi new to this, so excuse the elementary question

Can I put custom software on a XM122 using the XB122 dev kit?
This is the only hardware I have, is nRFUtil my only option to push software to the XM122?  Seems like the other tools need different dev boards or debugger interfaces.
If so, what is the best tool to build new hex files on a Windows platform, and some pointer to a sample of doing this?

Thanks

Cheers

Hi Andreas,

If you have not used a J-Link yet, I think the bootloader should still be present on the device, since the bootloader should not be able to overwrite itself.

To do DFU over Bluetooth Low Energy (LE), as the tutorial explains, you need to have Bluetooth LE supported when in DFU mode.

Do you know if the last firmware you uploaded to the device has support for sending firmware over Bluetooth LE? (Also known as Firmware Over the Air (FOTA)

Do you know if the Bootloader has support for Bluetooth LE  (Not in the application, but in the bootloader?

Oops, I managed the same, I also pressed Verify instead of reply, hope you can see this reply and reopen.

I am not 100% sure, but I did use my Android phone and nRF Util to DFU the device, so I assume the bootloader has BLE capabilities.  But I have tried that again, and currently cannot see the device in nRF Util on my Andoid, hence I assume it has been overwritten with my last DFU

Cheers

Hi,

Can you send the last zip file you uploaded to the device before it stopped working?

Last time you uploaded firmware to the device, did you use serial(cable) or Bluetooth(mobile)?
