Over the air (OTA) bootloading update tutorial?

@Suresh-Mali I have the same problem. Only I2C IC is available in my country :(
Looks like we have to hack the code. I will inform you when I reach this phase in my project.@ahmedadelhosni Great, do let us know once you have something.

Looks like we have to hack the code. I will inform you when I reach this phase in my project.@ahmedadelhosni Hey, I found this article. Seems like the guy has used i2c for remote flash. I was not able to extactly understand whats going on, maybe you can help.

nice catch ;) yes it should work with some tests and code changes in mysensors lib to write into the i2c flash instead of spi flash...
@scalz , Thanks:smiley:
I am not a Device Programmer, I am counting on some one to hack and make it possible. Hope somebody puts in efforts that will help everybody like me. -
@Suresh-Mali : yep, I understand :confused: unfortunately, I have no time, even if it is maybe not the biggest thing, tests take time..there are so much things I would like to do! Do you have a soldering iron??? What I have showed to you in previous post don't need big soldering skills...

@scalz Oh yes, soldering is not an issue. I have rework station and I am proficient with soldering Through Hole and SMD components.
Its about getting the EEPROMs.Buying from Ali would be my last resort. I am hunting for this chip in other parts of India. I should have an answer by day end, If I dont get them then I'll order from Ali. Waiting is the worst part of ordering from Ali. I had Order ATSHA204 on 12th Dec and still waiting.:disappointed:

Hey Guys, I managed to find a EEPROM chip from Bangalore, India. Its 25LC512, priced at Rs.65(~$1). I hope it works. I should get it next 2days. It has the same footprint as one used in SenseBenderMicro. Will try once I have them and update.

nice catch for the I2C bootloader.
Keep us updated please of your progress. I can't actually start this phase now as I am working on other things at the moment.
Good luck. -

@Suresh-Mali please do not post the same question in more than one thread. Answer is available in http://forum.mysensors.org/topic/3060/home-made-ota-and-authentication-breakout-board/2

There is several alternatives in aliexpress to the memory @Anticimex posted above, SPI interface, same pin distribution, only change the memory capacity and voltage input. (and good prices)
