I need a small Go program written to receive Bluetooth Low Energy (BLE) Advertisements. There is an existing open-source (GPL) library written in Go to do this, but (a) it contains too much additional functionality, (b) parses the BLE advertising data (payload) and doesn't provide access to the raw data/payload, and (c) GPL is unsuitable for my project which will be released under an MIT licence. The program will: 1) Passively listen for BLE advertisements (endless loop) 2) Call a callback function with the Bluetooth address, the RSSI, and the advertising data payload 3) For development purposes, the callback function will simply print the address, RSSI, and advertising data payload in hex. The Go program must work on Linux (Windows and MacOS support is not required...

We've developed a mobile app for Android. It's a point of sale app. We wish to add the functionality of printing different receipts using a thermal printer and the invoices (A4 format) using a desktop LAN printer. For the connectivity, we want the printing module to be able to connect to different printers (thermal and desktop) using Bluetooth, WiFi or USB. there will be some UI to develop in order to add a new printer, configure or delete the old ones and to choose what printer to use. We want that the printer module be delivered in a stand alone package (a jar file for example) that we can integrate to our project.

...device is moving for gps, accelerometer, gyro & temperature. This time should be configurable. 2. If device doesn't find any change in position, then data should be sent 15 minutes, if no further movement, then 30 minutes, 60 minutes, 120 minutes and then every 240 minutes. 3. BLE should read new advertisement only and send to backend every 10 minutes in 4 hours. With new advertisement means that beacon emit same message every few seconds. So if device read and send that message in 4 hour period, then do not send that message in 4 hour period. This period is configurable. 4. Device should save BLE mac address and UUID to identify owner of device. If device moves without saved BLE, then send message to backend. 5. Crash detection 6. Store data sent to card for a day.

I have an apk which is designed to connect to an electric ebike via Bluetooth, and once connected, it can lock / unlock the bike in order to ride it. Before the app allows you to connect to the bike, it requires you to link your mobile phone and receive a code. Unfortunately, the phone verification server for the app was shutdown, so there is no longer any way to link your phone, and therefore no way to access the rest of the app (since the phone linking is on the first screen) The app is quite proprietary so i believe there must be some way to simply bypass this portion of the app and be able to access the rest of the app abilities without linking a phone number The unmodified apk is attached. Please review it and let me know a reasonab...
