Re: Uart reading issue

Hi,

A day ago there was an update in the IDF to fix this issue. I haven't got around to testing it yet.

Query about OTA

Hi,

I have 2 partitions for OTA.
By default, ota_0 is programmed and runs.
After I perform an OTA update ota_1 is the running partition.

Is there a way I can jump back to ota_0 without rewriting the firmware to the ota_0 partition and run the old code?

Regards

Re: Uart reading issue

Hi,

I am facing the same problem. As long as I don't let the buffer get full it works perfectly.
I haven't found any solution for that yet.

Re: Magic Byte bin file

Hi ,

So is it safe to use this byte as the start of the bin to detect the end of http headers for OTA update?
