Re: BLE low power status

If you wan't always on BLE advertiser, the theoretical lower limit of the ESP32 is ~0.8mA (per section 30.3.9 in the TRM). This the lowest it can ever go. In reality, my estimate is on the order of 1mA. For most BLE applications, this is insanely high.

Re: Gripes on ESP32/ESP-IDF

How often do you read gyro & accel data? Are you sure that you catch the new data every single time (you don't miss every second for example)? How powerful was the CPU you were using? I worked on quadrotor uav 8 years ago. I used to read adc at 1kHz gyro+accel+mag, then apply a complimentary filter...

Re: BT and WiFi bandwidth speeds

Have you read this documentation?

Re: ESP32 not ready for production

FreeRTOS works only with tick frequency. Once you need to wait for something inside a driver you will wait for 1 ms with 1000 Hz tick frequency. In FreeRTOS you can get microsecond-level responsiveness... You can study this: https://www.freertos.org/a00124.html I have written hobby code for quadrot...

Re: WiFi with automatic light sleep

looks like you are getting a beacon timeout from the AP. Issue seems to be with your AP. more details here: https://esp-idf.readthedocs.io/en/v3.1-beta1/api-guides/wifi.html#wi-fi-reason-code You can try these things: 1. check to make sure the beacon TIM interval is 100ms on your router/AP 2. Try a ...

2. What RSSI are you at when this happens?

Re: Sending adc data (wireless)

I see... You are trying to cut out the middle man (the router), to get faster speeds.

I haven't done any raw 80211 frames, so you are already ahead of the game. If you can get it working, would love to see what results you get.

Re: Bluetooth Xbox One controller connection to ESP32

Looks like you are correct.. the Xbox One S controllers (after August 2016) are using bluetooth. Interesting indeed! https://fccid.io/C3K1708 https://support.xbox.com/en-US/xbox-on-windows/accessories/connect-and-troubleshoot-xbox-one-bluetooth-issues-windows-10 https://www.reddit.com/r/xboxone/comm...
