Thank you! That really helped

Hi, I need guidence. We are making IoT infrastructure with ESP32C3, ESP-IDF. I need MQTT WSS, MQTTS and HTTPS requests. So far I used OpenSSL to peek cerificate of servers and extract PEM file (examples). Everything is working. But how should it look like in production code ? My idea: do the same on...

I made one test - tried to connect, send, reconnect. After setting refresh_connection_after_ms: mqtt_cfg.network.timeout_ms = 10000; mqtt_cfg.network.reconnect_timeout_ms = 10000; mqtt_cfg.network.disable_auto_reconnect = false; // mqtt_cfg.network.refresh_connection_after_ms = 25000; it started wor...

Hi, I have done registration to DPS, procedure of refreshing SAS tokens and sending telemetry to IoT HUB. It worked for some time. After several days it stopped working. There was several failures. One success and then no more success. I isolated problem by writing desktop Pyton script which is real...

Hi, I'm working under USB connectivity. I need 3 stages: - (host) during boot if bin file is present on flash drive upload it and reboot, - (host) when app is launched use flash drive MSC to store logs, - (slave) when master is detected with additional circuit, set device in CDC mode. I would prefer...

Hi, I was trying hard to create build process that will speed up development. I wanted to test platform independent code on native. In the repo there is described process of testing custom ESP-IDF components in C++ Environment Status Duration ------------------ -------- ------------ esp32-s3-devkitc...

Hi, it turned out that ESP Box Light is in some way broken - I got it from official Ali store.
Now I got S3 Devkit V1 N8R2 from reseller in Poland and it is working perfectly fine.

Hi, I bought mentioned box in Official Espressif Ali Store. Programming it using USB-C is really tedious. I stared with online tool which wasn't working at all with USB C. Then tried with platformio and esptool. After several attempts with different upload speeds progress reached several % and faile...

Thank you for quick reply. Reference documentation is what I needed, and ofc comments in code. Not everything is clear to me, but it started clearing out as I'm working. I've bought some books but they are mostly focused on playing with ESP. One book about concepts of IoT was quite helpful. Document...

Hi, I'm software engineer in medical related company. We would like to introduce data logging for our products using ESP32C3 and MQTT. I used to work with STM32 and don't have much experience with ESP32 despite some Arduino projects. I've briefly read doc https://docs.espressif.com/projects/esp-idf/...
