Hello, In one of my prototype designs, I used the ESP32-WROOM-32D's U2TXD/U2RXD serial port to communicate with another MCU and the U0TXD/U0RXD pins to program it with an FTDI board and read serial data over UART (Arduino IDE, Serial Monitor). I also used the Bluetooth communication to send some dat...

Again thanks. as you mentioned the pico should have a lot of components already integrated but I could not locate a circuit diagram with esp32-pico-v3 or pico D4. Maybe I am looking into the wrong repository. Would it be possible to direct me to the resource page of espressif where I'll be able to f...

Thank you. Is it the "Pico D4" version of the MCU? Please correct me if I'm wrong, so in a way, 1. if I just connect power and an antenna I should be able to use it as a stand-alone MCU? 2. And In the case of programming the board I'll just use an FTDI board and to enable the programming mode I'll j...

Hello, I want to design an ESP32-based BLE UART circuit just like the HC-05 module. I have a confusion regarding the hardware and software parts. Each esp32 module has an external flash memory chip. Is it possible to program the barebone ESP32 IC without the external flash memory chip using Arduino ...

Hello Piyush,
Again thanks a lot . I'll give it a try and let you know.

Hello Piyush,
I think that was the mistake. Now I have downloaded it through git clone and it's compiling just fine.

Thank you.

Best Regards,

Thank you all, but I am now facing another issue. I have installed the Android Studio. But when I tried to build it, it showed me this error: > Process 'command 'git'' finished with non-zero exit value 128 I have found a solution online: https://stackoverflow.com/questions/35029768/glide-process-com...

Hello Everyone, I was wondering whether we can put multiple sensors to a single device. It might feel a bit confusing. So, I'll try to explain. Right now if I load the "multi_device" example code to a single ESP32 board, it actually creates 4 different devices in the esp-rainmaker app. It makes sens...

Hello Piyush, Thank you for your reply. Is the android app for the ESP RainMaker, Opensource? Then do you think that I can add some custom icon there directly? At least for now that can be one solution for me. If that is possible then I would really appreciate it if you can send me the git link for ...

Hello Everyone, I was wondering if there is a way to add a custom icon or image to an existing device or a custom device. For example, if I create a device, that is supposed to read a push button status from an I/O pin and also has to turn ON or OFF a LED based on the button status, I want to have a...
