Re: Differences between Nimble and Bluedroid, and a question.

Take a look at blemouse2xac which reconnects bonded BLE mice without pairing.
It is an Arduino program but the logic should applicable.

Re: Using Bluetooth HID with ESP32

I was able to get a BLE mouse working using this code. Thre is an example for a BLE joystick/gamepad.

And there is another example.

Re: USB host EP 0 STALL

The Xbox 360 controller is generally a human interface device but is not a USB HID. bInterfaceClass must be equal to 3 for a USB HID.
My Xbox 360 cheap clone is a vendor specific device. I suspect authentic Xbox 360 controllers are also vendor specific devices.

Re: USB Host example on ESP32-S3-DevKitC-1

Look at the link for how to wire up a USB host connector on S2/S3. A USB OTG host cable is not sufficient because the USB port does not provide VBUS 5V output.

Re: ESP32-S3 USB host interface to keyboard

Take a look these demos. Not complete implementations but maybe enough to get started. The code is for Arduino but is mostly C code that can be used with the IDF also.

Re: Trouble with SoftwareSerial. Alternative recommendations?

I use hardware Serial2 pins RX=16,TX=17 on a SparkFun Thing ESP32.

Code: Select all

Serial2.begin(115200);
...
while (Serial2.available() > 0) {
	Serial2.read();

Re: parse http data from website

Wunderground previously supported a free HTTP API to return weather data in JSON. It was easy to use and many demos/example programs used it to create WiFi weather display stations. This service is no longer free so scraping the weather data from HTML is one option. Another option is to use openweat...

Re: How to connect USB keyboard to ESP32?

I have been experimenting with using a SAMD21 (Trinket M0) in USB host mode to do something similar. The keyboard data (ASCII or USB HID report) is exported via UART so the ESP32 or ESP8266 does not need to know anything about USB host mode. Also this means it works with MicroPython, Espruino, Ardui...
