BLE_uart example does not create discoverable service when devices are not connected

I am trying to connect two Adafruit HUZZAH32 ESP32 boards via bluetooth. Therefore I use the BLE_uart and the BLE_client example. The problem is, that the BLE_client does not find the service of the BLE_uart board. Just to be clear, the address is visible, but not the service UUID. I also tried it w...

Re: What is the normal duration for first "make all" in Eclipse?

Do you know any factors that may contribute to this abnormal build time? CPU is running beneath 10% capacity.

What is the normal duration for first "make all" in Eclipse?

I am just starting using Eclipse with the ESP IDF. Following the steps in the tutorial and Neil Kolbans Tutorial I tried to "make all" the gatt_client example for the first time. Building this took 1h:20min. Is this normal? The CPU was not working on full capacity, so I don't think it is my computer...

In my project I'm using the Adafruit 2,8" cap touch display . It has an interrupt pin which triggers, when the touch screen is touched. Now I tried to use it with an Arduino Nano and had the problem that with the Arduino it is not possible to get I2C data from inside a ISR . My question now is, is t...

Re: simple beginners questions about ESP32 - Arduino

so i need to write : "attachInterrupt(digitalPinToInterrupt(interruptPin), & handleInterrupt , FALLING);" then? (by & referencing then?) Grtz, Yves Markonian meant that "void handleInterrupt(void * pvParameters)" takes the argument "pvParameters", but you can't call a function with an argument. So ...

Equip ESP32-WROVER-KIT with touch

I am thinking about purchasing a ESP32-WROVER-KIT for a project which needs to be equipped with a touch screen. I found this http://www.buydisplay.com/default/3-2-inch-capacitive-touch-panel-wiith-controller-ft6236-for-240x320-dots touch panel as an addition to a screen. I can't find any information...
