Re: Meditation Guru exception on SLIST_FOREACH

Figured out the issue: This is stack space issue because main has a small stack. And because this application was in C++ using a pThread instead of FreeRTOS directly resulted in the component running. On to debugging the rest!

Re: Is it recommended/practical to use C++ instead of plain C ?

PPS The first C++ project I worked on was a disaster. Noone knew how to approach C++ except the man we followed, turned out he had a text book under his desk. Thanks for challenging my assertions. Yes you are right. C++ is a tight and useful language for mid size to large projects where design patt...

Re: ESP32 still connects to repeater even when its signal is very weak

You can use RSSI to determine which connection is strongest and control connectivity in your code.

Re: Exception decode problem

Nice find!
I hit the same issue in my post previous to yours and you gave me insight into why.

The change you made was to make the ported code use index[1] correct?
A stroke of luck you had the same issue I did at the same time!

Thanks in advance!

Meditation Guru exception on SLIST_FOREACH

I am porting a C++ library to ESP32 and hit an exception on SLIST_FOREACH macro in 2 instances in the pthread_local_storage library. I am using the latest IDF build. I am not calling this code directly. It is called within the module. My only clue is that list maybe null but how could it if pthread ...

Re: OTA update without internet/WiFi network

I coded a comprehensive OTA solution for a consumer embedded appliance vendor this year. The serious flaw in your strategy is that anyone can brick your device by updating the firmware. In your design you have accounted for no security. Security is a big deal in professional OTA solutions. If you do...

Re: Is it recommended/practical to use C++ instead of plain C ?

I am in the process of porting a C++ library to ESP32. So far it has been OK however I hit a run time error with a macro for looping which causes a Meditation Guru exception in the PThread class. The perks of C++ are welcome however I am not fond of the bloat associated with C++ in a resource constr...
