Update firmware from flash

[abosch]

Hi all,

I'm using nrf51822, sdk 6.1 and s110 v7.1.

My idea is to use the GPRS module of my board to receive the new firmware (the module works with UART), save it to the flash(if it's needed) and then update firmware to the new one. How is the best way to do this? Which example can I use? I'm very familiar with OTA firmware update but in this case I don't know how to start.

Thanks in advance,

Aida
