Re: Get BLE UUID for iOS pairing

Sorry for bringing the topic back on, but the original poster has a point: While scanning for an ESP32 Advertising device using nRF Scanner (or BLE Scanner) - on Android Phones, you indeed get the MAC address of the device. However, when you scan for it in iOS using the same apps, you don't get the...

That means I need to forward all the data over my network to a central location - should that be a web database? local database? flatfile? Can it be collected directly on the android tablet or should I store it elsewhere? Where I can learn more about my design choices for aggregating and storing da...

Re: Calling esp_sleep_enable_gpio_wakeup rises power comsumption about 1.5mA

The pins are grouped into four power domains: VDDA (analog power supply), VDD3P3_RTC (RTC power supply), VDD3P3_CPU (power supply of digital IOs and CPU cores), VDD_SDIO (power supply of SDIO IOs). VDD_SDIO is the output of the internal SDIO-LDO. The voltage of SDIO-LDO can be configured at 1.8 V o...

Re: ESP32 Arduino code protection

Actually arduino-esp32 is LGPLv2.1, which means you should publish source code and make it publicly accessed:

Re: How to use GPIO Interrupts using ESP32-S2?

There should be no difference to attach interrupts for S1 and S2.

Re: Unable to connect to local MQTT broker via websockets example - invalid header=0x48

Did you try to set esp_mqtt_transport_t in esp_mqtt_client_config_t. I think its default to TCP or SSL.
