Esp32 as arduino programmer

I would like to use the esp32 as the gateway to internet and have esp32 connected to an arduino RF module with its own atmega328p processor. Is there a way for me to update the arduino RF module over serial between Esp32 and arduino. Like emulating AVRDUDE over serial. And triggering this to happen ...

I am using the Arduino IDE version of the SDK for ESP32. The time it takes for me to get an IP address is usually around 1000 - 1050ms (using WPA). The time it takes to connect to an MQTT broker varies. Anywhere from 1.4s to 3s. I am using cloudmqtt.com for a test connection. Does anyone have any be...

Re: LoRa communication between 2 esp32 using a LoRa module

I am wondering on a more fundamental question your application. Why would you use LoRa as a bridge between 2 ESP32. LoRa modulation requires a 1% duty cycle and depending on your amount of data you should not be transmitting that often. ie, 1 second TX time = 100 seconds wait time before being able ...
