Description of radio waves
Blette can publish messages to people around you who can receive BLE5 radio waves. If you have fun or trouble, let's publish a message. You can publish messages to people around you even in environments where wifi or carrier radio waves do not reach.
If you set it to the same group ID as your friends, you can only display messages from your friends. You can see the message you want to see immediately and check where your friends are on the map.
I don't use carriers or servers

What technology are you communicating with?
It communicates using Bluetooth5 coded phy (LongRange) technology. It is now possible to communicate with Blette installed on Android without a carrier communication network such as 4G or 5G or wifi connection. Since the communication condition improves as it gets farther from the ground, holding it higher will improve the communication condition.
We have confirmed the transmission and reception operation with Samsung S10, S10+, S20, S21, and S22. We have confirmed the transmission of the message on Google Pixel4a and Pixel6a. In the future, we plan to announce a USB dongle that enables long-distance communication by attaching it to each company's Android terminal.
