Re: Using Ethernet LAN8720 and I2S Audio at same time

I am running into the same issue now. What was the pinout you have for the Ethernet and i2S ? I am trying to hookup a LAN8710 and max98367a together.

Thanks

ESP-MESH + ESP-NOW

My only knowledge of the ESP32 is using the Arduino IDE but I am interested in ESP-MESH and ESP-NOW. ESP-MESH sounds like its not really designed for battery powered devices. Its more like Coordinators and Routers in Zigbee/Zwave. ESP-NOW is for battery powered devices? Is it possible to run ESP-MES...

ESP32 + max98357a + online MP3 for Google TTS

I am trying to use the Google Text to Speech API and generate an MP3 file from Google and then play it on the ESP32 with MAX98357A connected. Someone below wrote code to somewhat do that but I keep getting Watchdog errors or other errors: https://github.com/oroca/oroca_can https://www.youtube.com/wa...

Re: Esp32 update attached arduino?

A pipe is not really what I am looking for. I am looking for more of a way to have the esp32 get a HEX file from the cloud and store it locally and push it to the ATMEGA328P. The link looks interesting but I see it uses SPI to program the chip instead of serial. having SPI always connected between t...

Esp32 update attached arduino?

Is there a way to use the esp32 to update a connected arduino over serial ? I know it sounds redundant but I have an RF module made and uses an arduino core and i want to be able to update the module if theres any updates available online. Is there a similar function like avrdude to program a 328p? ...

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 ...

Connection time, MQTT connect time, and current draw?

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 ...
