On the fly OTA example

[SBS.1]

Hi,

I am working on STM32 with Quectel GPRS module.

Now I have to implement OTA without using any external flash or SD card.

Is there any example for GPRS based OTA without using any external memory to park the bin/hex file and program the MCU flash on the fly.

Regards,

Does the modem have it's own mass-storage memory into which it can FTP download the firmware or deltas, and then apply them from there?

Going to be a tad challenging it you have now way to stage it, and the modem doesn't participate.

Pretty much you're going to have to read the instructions, and implement the code to perform them.
