Thanks, ChatGPT! But I'm embarassed to say my bug was a floating point precision issue. I had a stray float in my time_t -> double calculation, and when SECONDS was large enough, the fractional MICROSECONDS was being discarded, and was internally always zero. That's why it always matched! So... my b...

I've got an app (NightDriverLED.com) that relies on syncing time amongst multiple ESP32s via NTP. I've found they cam remain accurate to 1/1000000th of a second (0 microseconds) over 30 minutes, but sometimes, something happens that they shift several seconds, like 6. I have no idea what causes it. ...

Thanks very much! I was confused by having seen the higher available counts on the S3 version, not realizing it's a significantly different chip!

I'm using a WROVER-E-N8R8 (8M flash, 8M PSRAM) on a custom PCB. The code manages to initialize PSRAM, but it only finds 4M, not 8M. I'm using PlatformIO, though an Ardunio build. But the same code works on an 8M ESP32-S3 and reports 8M. Is there anything special or particular I can or need to do for...

My app just crested the 1M boundary, and I'd like to keep OTA functionality. I also need about 1M of spiffs. I created the following partition table and it flashes and runs fine over serial, but when I try to OTA, it fails in Begin when it's considering the partition table. I presume it things I don...

I have long used: platform = https://github.com/platformio/platform-espressif32.git However, I recently found that there is: https://github.com/espressif/arduino-esp32 What I'd like is a stepping stone off of the classic Arduino SDK and I thought perhaps this was it - a way to build for esp-idf with...

I'm getting very rare and sporadic failures from multi-heap (BAD HEAD, etc). I'm hoping I can somehow enable heap corruption detection and tracing when using the Arduino platform.

Is it possible? Any magic value for build_flags perhaps?

Thanks!

I see a lot of ASSOC_LEAVE, which I thought was load balancing, but once I added printing of the BSSID, I can see that each time it's the same nearby access point. Does anyone know why it always takes me 3-4 attempts, over a total of about 10 seconds, to connect to the AP? It connects and then disco...

I defined a simple "print error and abort" routine that unfortunately never seems to print anything. Is there anything obviously wrong with this approach? Thanks! inline void DelayedReboot() { Serial.printf("** REBOOT **"); Serial.flush(); delay(10000); exit(0); } // For catastrophic failure, wait 1...

I'm having two problems with the IRRemote library (ID=4). If I enable it before WiFi is started, it will blow chunks (ISR touching data that's not paged in). Same problem with the ESP Async Web server. As soon as the web server goes to process a request, if the remote has been enabled, it dies a sim...
