Re: Question about esp32.com forum
Hi rudi,
thanks but unfortunately youtube don't give me a youtube.com/user/pcbreflux for my user pcbreflux only https://www.youtube.com/c/pcbreflux.
Ok, its only cosmetic but it would be nice to enter a real URL in the setting to avoid this.

Re: Communication between two Bluetooth/BLE devices
Hi, have you tried the gatt example? The esp32 as a gatt server let you connect from your phone to the esp32: https://github.com/espressif/esp-idf/tree/master/examples/bluetooth/gatt_server Maybe this is what you need? (start easier without "Use raw data for advertising packets and scan response dat...

Re: Getting Started with BLE on the ESP32
Hi, the easiest way to run make is to put the PATH and IDF_PATH to your $HOME/.profile: like export PATH=$PATH:~/esp/xtensa-esp32-elf/bin export IDF_PATH=~/esp/esp-idf then run . ~/.profile once or logout/login or restart the computer In the examples mostly the needed settings are made. Sometimes ju...

Re: [Video] ESP32 - Using displays and the U8g2 library
For anyone else with the 128x32 I²C display:
I've done a 10h loop test and my display works even stable with 1Mhz I²C i.e.:
(50kHz was just a test for my function analysis with Sigrok /PulseView)
see u8g2_esp32_hal.h
#define I2C_MASTER_FREQ_HZ 1000000 /*!< I2C master clock frequency */

Re: Which OS when focusing on Bluetooth + Wi-Fi?
Hi, think the OS don't matter for programming but I am using Ubuntu. See others using Windows and iOS or Ubuntu in a vitual box. For BLE discovering I use a Android mobile APP from nordic "nRF Connect". For a small BLE/WiFi example with esp-idf you can watch the samplecode here https://github.com/pc...

Re: [Video] ESP32 - Using displays and the U8g2 library
So my first pull request is online. After reading about forking and branching with git the rest was a piece of cake (for a command-liner).
Thank you.
Thank you.
