[Solved] Strange behavior of RFM69 OTA burning firmware after some research

@yury Please try with this, I've quickly added a check:

~~https://github.com/tekka007/MySensors/tree/OTAUpdate~~
~~PR: https://github.com/mysensors/MySensors/pull/718~~

Edit: PR merged, try with the latest development: https://github.com/mysensors/MySensors/tree/development

@tekka

with your new PR updated all works good now. I could not replicate @ 40 ms in retryWaitTime the mentioned above. so I put 10 ms like a stress test. It has survived! with lots of WRONG FWB but with CRC OK!

Just 2 cents... We couldn't replicate 40 ms in retryWaitTime the mentioned above in another location. And tonight Yury couldnt replicate this case at home too. But yesterday it was typical situation. So I can assume it was caused by high environment radio noise (city center with many potential RF sources). I think it is an ideal situation to test boards and improve library stability :wink:

@yury @Koresh Thanks for your feedback and thorough analysis, that helped to identify the issue.

Hi,

I might be a bit dumb , but I can't find RFM69 OTA bootloader ?

Has anyone done it ?

[scalz]

@napo7
this is sensebender micro bootloader, same as dualoptiboot from lowpowerlab

[napo7]

Ah ah ! I was sure that I was dumb !!

I'll have to give a try to port MYSBootLoader to rfm69 so ....

[tekka]

@napo7 There is something cooking in the lab...will post more in a bit :)

[napo7]

Well, I'll wait a bit, so !

BTW :how much is a bit for you ? :laughing:

[tekka]

@napo7 Hmm...1/8th of a byte ;) I cannot give you an ETA right now, but feel free to write your own bootloader implementation of the RFM69 driver.

[napo7]

Well done ! I must admit I wasn't ready to read such a word play ;)
Hum... In fact, I did a small try, cloned the RF24 bootloader, tried to search which pieces of the code I have to modify, but didn't go further....
If you was about to release it in the future days (I'm willing to help/debug/test), I'd have waited, but my projects are going to be on a rush....

I'll try to go a bit further in making my own version :)

[tekka]

@napo7 perfect!

[yury]

The bootloader and OTA update script + RFM69 work super nice with MYScontroller. I use it few times a week. Big Big Big ups to Tekka. Especially I like the sensebender micro bootloader boots instantly ))). Enjoy everybody!

Hi @tekka,

Any news about RFM69 for MYSBootloader ?

I've had another look in the code, too much complicated for my skills !

[tekka]

@napo7 No, nothing that is close to a release - I've done some PoC with rfm69 bootloading but this needs more time.

Hi @tekka
Would you share your poc so I could try to enhance it ?
