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

The sixth prize of 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 gather 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, indoor navigation, and more.

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

It allowed me to send commands through MQTT topics, for example, to set or retrieve the beacon’s (WiFi) configuration, and receive the data through MQTT subscriptions. Some of the data include the MAC address, RSSI, ad (Broadcast data advData), and a timestamp. It took some effort to get it working, but I eventually managed.

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

To enter the draw simply leave a comment with your country and whatever else you’d like to say (no links in the body of the comment). If the country is missing, I’ll consider the entry void. Other rules are as follows:

• Only one entry per contest. I will filter out entries with the same IP and/or email address.
• Contests are open for 48 hours starting at 10 am (Bangkok time) every day.
• Comments will be closed after 48 hours. If comments are open, the contest is still going on.
• Winners will be selected with random.org, and announced in the comments section of each giveaway.
  
• I’ll contact the winner by email, and I’ll expect an answer within 24 hours, or I’ll pick another winner.
• Note that I may not be able to contact people who log in with Facebook, Twitter, or Google, so it’s better to use an email address to enter the draw.
• Shipping
  • $14 for registered airmail small packet or ePacket for overseas shipping payable via PayPal within 48 hours once the contest (for a given product) is complete.
  • If your country does not show up in the list of supported countries, you can still play, and I’ll cover the cost of sending the parcel by Sea and Land (SAL) without registration if you win.
• I’ll post all prizes at the same time, around the 16th of November, except for products shipped directly by companies which will be handled separately.
• I’ll make sure we have 7 different winners, so if you have already won a device during this giveaway week, I’ll draw another person

If you don’t end up winning this giveaway, the GL-S10 Bluetooth IoT Gateway is sold for $24.99 plus shipping, or $29.99 with the BLE beacon.
