Hello everyone.
I need to send simple strings to one esp32 from the other (one is wroom 32 and one is wroom 32d)
with Arduino IDE.
If you can, please provide me with a simple code for this communication because the code I found is so hard to understand and has too many lines.
would not recommend BLE it is far simpler to use a WiFi protocol such as ESP-NOW
for BLE have a look at File>Examples>ESP32 BLE Arduino>BLE_server and BLE_client
Thank u.
Unfortunately I have to use some sort of Bluetooth communication.
for BLE the BLE_server and BLE_client should give you a start
for Bluetooth Classic have a look at File>Examples>BluetoothSerial
this esp32-ble-server-client-communication example may be useful
