Re: loading AWS certs from SPIFFS

Probably not encrypted, unless you're using flash encryption on the ESP32. Are the certs in PEM format? (if so they should be plaintext readable)

Can you please share the code you're using to print the certificate contents?

Re: doxygenfunction: Cannot find function “i2c_slave_read”

Hi rudi, Some URLs changed between v2.0 and v2.1, when we cleaned up the documentation in general (including removing these warnings). Unfortunately RTD doesn't give us an easy way to forward the old URLs to the new ones, so switching versions sometimes gives these 404s. v2.1.1 is a bugfix update to...

Re: Hardware problem: Program only works when serial monitor is open

Without a schematic it's impossible to really say. However their automatic reset circuit is probably implemented with 2 of the 3 SOT23 transistors visible on the back of the PCB. The third transistor is probably for managing access to the SD card slot. I expect if you desolder the two transistors yo...

Re: Weird monitor behaviour with printf on IDF 3.0

I may know what this is. For some reason, after the Fall Creators Update Windows 10 idf_monitor.py started sometimes randomly throwing an exception after writing to the "standard output" console. This is the OS telling us the write failed, for whatever reason. On investigation, people noti...

Re: Socket outgoing buffer overflow

For UDP sockets, there is a behaviour where send() may return an error with errno set to ENOMEM if the outgoing driver layer transmit buffers are full. Sleeping for a single tick and then trying again is the best solution if you get a failure with this errno value. You can also increase the number o...

Re: ADC input minimum current

ADC input current will be neglible. However, to get the most accurate results from a high impedance source (like a high value voltage divider) you can add a small buffer capacitor (approx 100nF) between the ADC pin and ground.

Re: Failing to allocate memory for RF calibration data when reiniting WIFI

Hi mr1000, I'm not sure that it's safe to fully de-initialize WiFi in the context of the event handler itself. You may have to signal a different task to do this, if you need to. However, I think fully de-initializing shouldn't be necessary - that's fairly extreme "scorched earth" tactics!...

Re: Python issues - ImportError: No module named site

Thanks nathan. This all looks correct to me, I can't really explain how it's failing to import built-in Python modules. Did you download and unzip the all-in-one environment and toolchain from here? http://esp-idf.readthedocs.io/en/latest/get-started/windows-setup.html#toolchain-setup Is it possible...
