I have a very simple application where one ESP32 sends a message over BT to another ESP32. I have been playing mostly with Arduinos till now and using that this kind of application was quite easy, but now I want to move to this platform. Using BluetoothSerial.h library I can happily ...

I am using ESP-NOW to communicate two ESP circuits. My aim is to get more gain trying to attach external antenna to AiThinker ESP-C3-13 Node MCU kit. Module is coming not soldered male interface on board. Therefore I soldered an IPEX connector to board. After the soldering connector I...
Communication between two UART devices may be simplex, full-duplex or half-duplex. Simplex communication is a one-direction type of communication where the signal moves from one UART to another. It doesn’t have provision for the receiving UART to send back signals. A full-duplex is when both...
Now you need to connect your ESP32 Bluetooth adapter to your target device. Choose the target you want to use (Nintendo Switch, PlayStation 4, or another device with Bluetooth) and follow the steps. Pay attention to the status of the adapter in the lower-left corner. 'Remap is ON' shou...
I'm using an ESP32-C3 chip but running into issues because of the boot messages that are automatically sent to the non-USB UART on boot up. I use this UART to communicate with another device and these messages are causing its communications to fail. ...
Another Question: The only thing I can't understand at the moment is if I need to go through the MFi process just for development to use ExternalAccessory? In terms of creating a fully MFi licensed accessory the answer is, yes. You'd need to join the MFi program to get access to the...
SOCORAD32 can communicate between devices by voice or text for up to 5km, via license free bands. Earlier in the monthwe postedabout how rtl_433 has been ported to ESP32 devices that are combined with CC1101 or SC127X transceiver chips, such as the low cost LILYGO LoRa 32 boards avail...
How to use the LCD1602 connected with the ESP32 via the I2C. We will see how to use the function to write the data to the I2C slave...
The ESP32 connects to the WiFi network of your router and gets assigned a unique IP address that can be used to communicate with other devices on the network. Set The ESP32 in Station Mode (STA) To set your ESP32 to work in station mode, you need to call the WiFi.mode(WIFI_STA) ...
