Have a look at this too:

The IDF I2C example has a function showing how to set up a standard multi-byte read like this:

Sorry rfleming, I was a bit quick on that. Yes I think the issue is that the default internal read buffer is 512 (DEFAULT_HTTP_BUF_SIZE) and the _perform() api will read right through the response. So the internal buffer will have only the tail end of the response when you _read() from it. I'm not s...

You read into buffer "data" then dump uninitialised buffer "tmp"

Recent changes in IDF [0] allow significantly lower light sleep current. Testing this today, I found some interesting behaviour I don't quite understand. The TL;DR is that this is a great improvement (825uA -> 375uA) but it seems it can be achieved much more easily by resetting a small number of off...

Isn't it likely that you still have power supply problems? That could cause odd behaviour with touch sensors, but you won't know about it now with brownout detection disabled. If you have a reliable reproduction for the brownout reset issue you should reply to @igrr: https://github.com/adafruit/circ...

Don't dwell on it, there's no leak if there's not a consistent pattern of reduction. See this post: https://esp32.com/viewtopic.php?t=14056#p55646 And also consider that there are other tasks doing work behind the scenes - especially WiFi/lwip in this case, which will be dynamically allocating/deall...

skip_cert_common_name_check will not allow you to bypass TLS, it will only avoid checking the certificate's CN (so a possible mismatch would not fail validation). To completely disable the certificate check, you will need to go to ESP-TLS in menuconfig, enable "Allow potentially insecure options" an...

Same as this? https://github.com/espressif/esp-idf/issues/6179
