Samsung smartthings capable esp32 smart switch
Experimenting with #Samsung #smartthings capable #esp32 smart switch using their SDK and ESP-IDF. There is no need for a hub, works directly with the Smart Things app.
Meet the PS Thermo
Meet the PS Thermo – my smart thermostat with a TFT32-based control hub and sub-GHz RF wireless sensors, the successor to BBoilRF.
Simulink modeled software component into an ESP32 project
Successfully integrated a rather complex Simulink modeled software component into an ESP32 ESP-IDF/Eclipse project via code generation. Pretty impressed with the outcome and how fast the SWC was developed this way. #esp32 #simulink #freeRTOS #embedded

Atmega328 OTA update over RFM69 wireless link
Experimenting with Atmega328 OTA update over RFM69 wireless link, works fine. Remaining is to implement this+GUI on the TFT32 esp32-rfm69 gateway project, so it can reflash the relay actuators if needed.
WiFi AP association timeout on an ESP32 project
Had to increase a WiFi AP association timeout on an ESP32 project, it was failing to connect in <15 sec. What is the recommended time to wait before considering a connection attempt timed out?

ESP32 based thermostat controller/gateway project with TFT
It's close to a year since I started working on my ESP32 based thermostat controller/gateway project with TFT display. It now has 120K+ lines of code (components included), work done entirely at nights/weekends. What's the longest you have worked on a passion project? #IoT https://x.com/mharizanov/status/1027868368500666368

ESP32 serial log messages to MQTT
Implemented option to send a copy of the ESP32 serial log messages to MQTT; Makes it so much easier to debug remote nodes. Literally takes one line of code, look up esp_log_set_vprintf. Next is to provide API to change the log level runtime so I can focus on the desired component
ESP32 OTA rollbacks
Implemented ESP32 OTA rollbacks if the new firmware crashes within 45 seconds of first boot, doesnt manage to connect to MQTT or the device enters degraded operating mode due to failed hardware initialization. This gives me a peace of mind when pushing mass OTA updates. #IoT

x.509 certificates to dedicated ESP32 partitions
I now load x.509 certificates to dedicated ESP32 partitions rather embedding into the code via COMPONENT_EMBED_TXTFILES; This helps decouple the code from provisioning the device with CA and client certificate+key; Still working on PKI to provision the certificates at flash time
