Re: First post, BLE and LORA data collection and presentation, aggregating/storing data?

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...

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...

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.

Re: ADS1115 with espress-idf and esp32

I dont know which idf version you are using, but some time ago 1 more value has been added to "i2c_config_t" struct which is causing issue when i am trying arduino as component, because is not initilized. But this is issue with C++, in your case it may be something else (worth to try). I think its t...
