Giveaway Week – GL.iNet GL-S10 BLE to MQTT Gateway

The sixth prize for this year’s Giveaway Week will be GL.iNET GL-S10 BLE to MQTT Gateway based on the ESP32 microcontroller and offering Ethernet, WiFi and Bluetooth LE connectivity.

The gateway is used to collect data from Bluetooth LE devices such as beacons and can be used in warehouses, shopping malls, airports, exhibition halls, tourist attractions, etc. for personnel management, asset management, environmental monitoring, inland navigation, etc.

I saw the BLE to MQTT gateway based on ESP32 with the BLE beacon provided at the end of last year using MQTT X open-source client and the GL-S10 Tool app for Android.

This allowed me to send commands via MQTT topics, for example, to set or retrieve beacon configuration (WiFi) and receive data via MQTT subscriptions. Some of the data includes MAC address, RSSI, ad (advData broadcast data), and a timestamp. It took some effort to get it to work, but I finally got it.

The gift includes the gateway with its antenna and its USB cable, but I will not send the BLE beacon because of the non-removable 3.6V ER14250 1/2AA battery to avoid problems with customs. You can use other BLE devices for this purpose, and during testing I received BLE messages from a smartwatch or one of my air conditioners.
