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

Hi,

I'm in the process of getting the same functionality in place. I have a ZIP file at hand that upgrades through the mobile app successfully.

I have managed to use the GSM modem to download a binary file and store it into the nrf52 flash memory.

What is the next step? Can the firmware update process be initiated by setting certain flags and then resetting the chip?

Which individual files should I upload off the package?

I'm using SDK 15.

Thx

Eliav

Hi Eliav

We are now turning our attention to this project again.

Would you be able to share your progress (source code), so we can work together on the second DFU stage, and hopefully crack it faster?

Thanks

Hi  Eliav, 

i'm interested to your job. Can you share your job?

Are you save the hex file directly into flash of Nordic? If yes, i think you are using the dfu dual page, is it right?

Just wondering if there was any progress on this?
