# BLE gateway ## Compatible parts **The ESP32 has an integrated BLE module**, with this board the BLE gateway don't need any additional hardware. Making it the **advised board for BLE**. You can use a barebone ESP32 or some nice looking products like the ones below (from M5Stack): ![](../img/OpenMQTTgateway_M5_Atom_Board.png) ![](../img/OpenMQTTgateway_M5_Stack_Board_Display_Text.png) For Arduino and ESP8266, we previously used HM10, this module is no longer supported by OpenMQTTGateway, prefer an ESP32.
