I saw this video on YouTube: https://www.youtube.com/shorts/imEQYq-X4yA, and I searched for the device, which is called LoRa LR2021.
Normally, it's quite hard to show a video on a LoRa device, but the device looks like it can transmit video information between two devices.
It is hard to confirm what technology it uses, even though its name contains 'LoRa'. Maybe it's just WiFi Halo.
The device shows Codex usage over BLE: a GIF pet, a 5-hour usage bar, a 7-day usage bar, reset countdowns, and live state changes such as busy, idle, completed, attention, dizzy, heart, and sleep.
After adding the plug-in, the device will automatically connect through BLE
This kitty is generated by Codex, using the hatch pet skill with prompts
It's also available to upload other pets' GIFs.
I will update GitHub with a full tutorial soon or later
I use StickS3, and its chip is ESP32S3 by the way
I'm planning to use it while hiking. I heard it allows you to share your location on a map.
