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...

Did you try uart speed 115200, which is default esp32 speed?

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...

Maybe not exactly what you are asking for, but its good example to start to do what you want:

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...

I don't understand why ota require two partitions, the factory partition can't be erased and writen via ota ? Today via usb and idf.py utility I noted that my binary is writen on the factory partition: 0xf0000 ESP_MCU.bin If I start an ota update i'll write on ota_0 partition and boot on ota_0 pari...

Actually arduino-esp32 is LGPLv2.1, which means you should publish source code and make it publicly accessed:
https://github.com/espressif/arduino-es ... LICENSE.md

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

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