C3 and WROOM support different bluetooth protocols. WROOM supports Bluetooth v4.2 , and C3 supports Bluetooth 5. I think you can try the following example. It is for bluetooth classic in ESP32. https://www.theengineeringprojects.com/2021/11/esp32-bluetooth-classic.html This document may also help yo...

Hi, which library/code are you using?

The Guru medication error sometimes occurs due to a bad USB cable or inappropriate power supply. Have you checked them out? Here is also a thread that may give you some hints: https://github.com/espressif/arduino-esp32/issues/3634

Hi, it looks like many other people faced the same problem before. You may get some tips from here: viewtopic.php?f=18&t=5835

This is based on Arduino and DHT11. https://www.theengineeringprojects.com/2020/12/interfacing-temperature-humidity-sensor-arduino.html It explains DHT11's working principle, pinout, protocol and interfacing with oth...
