NRF52832 FOTA update via GSM

[modles]

Hello

I'm looking for someone to help write a custom bootloader which performs FOTA update by using an HTTP connection to collect firmware. NRF52 is connected to GSM module via UART.

Firstly, is this possible!?

Secondly, anyone available for contract.

Thanks

Ben

Downloading the firmware image through the GSM module is definitely do-a-ble, but most likely not through an http connection. One of the products (not nRF52) in my previous job was upgraded that way (mcu <--uart --> Telit GSM module <-- GPRS/GSM -- > socket listener on a cloud server. The custom bootloader has to drive the whole process, from instructing the GSM module to set up socket conenction to cloud server, to storing the downloaded binary image into internal (for 2 bank update) or external (1 bank update) flash, and potential recovery action if the new image fails to boot up.

Hi Matt

Do you have any example boot loader code for this? or would you be available to assist on freelance basis?

Thanks
