Ive been able to fix the issue.
All I needed to do was call:


nError = uart_set_rx_timeout(g_arrDevices[ucDev].stHW.nUART, 1);

Hello,

I was able to reduce the memory consumption by changing a property in the sdkconfig with 'make menuconfig'.


Component config -> mbedTLS -> TLS maximum message content length -> Reduce to 4096

Update to my post above:

I was able to create a simple mechanism / workaround, that gets the job done, but Im not sure if this is an optimal solution:

I also created a http server, which is ...

Hello,

I was developing a project recently which makes use of a http webserver and a wifi soft ap.

I observed that when there is data traffic on the CAN bus and I am doing a OTA update, the ESP crashes at the erase flash stage during update process.

This is the ...
