aws transport for dfu

[KentOverton]

I currently have a board using  a nrf52840 that has a reliable connection to AWS via a Quectel BG95.

I have DFU implemented and working via Bluetooth with config settings 

CONFIG_BOOTLOADER_MCUBOOT=y

CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU=y

CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU_SPEEDUP

I'd like to replace the Bluetooth transport with my AWS connection.

I'm  using SDK v2.6.0.

Could you please point me to a starting place to research this?

Hi,

I'm not certain how the module you refer to work, but here's a couple of resources that might get you started anyways: 

https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/net/aws_iot/README.html#aws-iot with focus on the fota section.

If this does not help, then in short terms: If you have set up your device with MCUboot, a primary application slot and a secondary application slot, you should be able to 

1. Enter bootloader mode
2. Receive the update image over AWS through the Quectel and write the image to the secondary application slot (on either external flash with communication to the nRF52840 for instance).
3. When the image is received, MCUboot tests and verifies the image and confirms it for swap at first reset of the device

Let me know if this is enough to get you started

Kind regards,
Andreas
