So as it turns out, the real reason my framerate on the audiolink project was so bad with 4 packets wasnt due to ESP_NOW. It was ACTUALLY due to serial capping out at 921600 baud, and that limits me to 600kbps. Need to figure out a faster way to send data from my laptop to the ESP transmitter

まだ buggy ですが(´・ω・`)

Ah - you're using the built-in Serial firmware (AT+) for controlling the ESP-01. If you program custom ESP8266 code, you can use ESP_NOW which is much easier for doing peer-to-peer networking. It also uses much less power compared to WiFi. It's basically raw packets on the WiFi PHY.

ESP_NOW doesn't work by SSID, it works by MAC.

The implementation of the ESP_NOW/i2c receiver has been started.

#ESP_NOW #M5Stack

gob_esp_now の racing ゲームの開始ができない場合があったバグがやっと修正できた。
fully 接続も追加したいところを我慢して、ドキュメントまとめて一旦 master 公開へ向けて進行しよう。

gob_esp_now を public repo 化しました。
まだ develop 版のみの運用です。
buggy だと思うので要注意です(´・ω・`)

Broadcast に対する送信が Core2 だけうまくいかない。

Core,CoreS3 では他のデバイスで受け取れるが Core2 では 他のデバイスに飛んでいないっぽい。(送信コールバックは共に成功が返る)

後ほどミニマムな再現コードを作って検証してみよう。

#M5Stack で #ESP_NOW パケットを Sniffing する奴ができたかな...。
Core0 WDT の回避と出力とキャプチャの速度差の吸収にちょい苦労した。
まとめて公開予定。

The WiFi remote controller works by ESP_NOW / I2C data streaming bridge between a pair of ESP32S3s and Teensy4.1.

The PitchValue on the instrument side is controlled via ESP_NOW/I2C from a rotary encoder placed on the remote control.

I was successfully confirm the Type:AN/PRC-6's compatibility with ESP_NOW. Also, the LEMO connectors on the front panel are more of a nuisance than I had expected, so it would be better to relocate the wiring for switches to the bottom of the body.

To solve the problem of not being able to read MacAddr of MCU connected to Arduino via USB_Serial, I made a trick to launch MacAddr read locally with ESP_NOW once and read the address with another MCU.

I have successfully experimented with a remote control unit that connects to Theremin via ESP_NOW via I2C.

This may be the first theremin in the world that can be trilled at a decent pitch.

I will experiment with ESP_NOW by producing device pairs with simplified functions on the transmitter side.

I implemented Transmitter on Seeeduino/Xiao ESP32S3.

Transmitting ESP_NOW is working fine for now, but I need to connect an antenna.

The check of the wired midi receiving function is not completed.
