Re: Mosfet choice

Hi guys, what you build would be the same as this https://es.aliexpress.com/item/10pcs-lot-Voltage-Sensor-10pcs-for-Arduino-DC-Raspberry-Pi-Amplifier-Digital-Current-DC0-25V-with/32801635174.html?spm=a2g0s.9042311.0.0.aRy6W6 ? Though I'm doing it for you, of course. I'd like to know if it's the same...

Neither do I, with how easy it is with arduino IDE, for example. Last week I downloaded the 256dpi/esp-mqtt complement and it appears in the menuconfig, but I haven't tried it yet to send it to thingspeak.

Re: Simple MQTT with C++ and IDF

With the aws iot, do you have to use it on their platform or can you use the mqtt portion for another service IE: mosquitoe? Also, did you implement it in c, or C++ with the snippets aws iot code? I've done some tests with the example of espressif https://github.com/espressif/esp-idf/tree/master/ex...

Re: Simple MQTT with C++ and IDF

Very good contribution, this component did not know it (I have tried paho, mosquito... etc) but I'm going to try it, because I don't care that don't have security support. I've been testing mqtt on AWS IoT and it's great, being integrated with IDF.

Re: Simple MQTT with C++ and IDF

Hi, I have the same problem, I've tried several mqtt libraries and managed to make espmqtt work but only with C code, not C++. But I have a problem, stop sending information to Thingspeak, about 15 minutes. Therefore, I still haven't been able to use the mqtt protocol because of this, I still use RE...

Re: About temprature_sens_read();

Thanks for the answer, ESP_Sprite. No problem, I only use this value to check the chip stability, I get the temperature and humidity with I2C sensors.

Re: ESP32 OTA via BLE

hello, although I suppose you have already thought about it, an alternative way is that the app installed on the client's smarphone, configure the phone as AP wifi with some keys that ESP knows and pressing, for example, the reset of ESP this connects to the smartphone and updates.
