Bluetooth broadcasting Jobs

We need a small temperature sensor that will be mounted under a home sink on the hot water pipe. When the pipe temperature hits 95 degrees F the device will send a signal approximately 3 feet to a receiver on the sink countertop. The receiver will have an LED that will turn on when it receives the signal.

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.

As already discussed

Hi, i have an existing app which...good. As you see on the left side :) The app is based on this open source Bluetooth serial monitor: If you are up for it and can do it fast. Let me know. If you can solve these two issues. That would give you a tip: 1. This app scans for Bluetooth devices. But it only shows devices if i manually give Location Permissions to the app (Under Android settings). Can't the app don't get these permissions during install? 2. This app connects to a Bluetooth device (ESP32). With older android versions (I believe 8 and lower) the app can connect automatically without pairing in Bluetooth settings. But with new Android versions. I have to manually pair the device in Bluetooth settings first. Any way around that?

Currently, we are using STM32L1 series MCU and another sensor. Now , need to replace STM32L1 series MCU with STM32WB10 (Integrated BLE) and establish communication with Android Mobile App. ...

A few salient features of the app are - 1) connects to a bluetooth device from user with a unique ID 2) measures the distance of the connected bluetooth device and points in the direction to the device 3) activates a speaker on the bluetooth device using the app . Shall share the UI pages of the app once we start the work .

I have an application on a tablet that reads and records the manufacturing temperatures of different elements. I need to record that temperature without having to type on the tablet. I need something that reads the temperature or an average temperature and sends it via bluetooth like a keyboard. I don't know if that is possible and what the cost would be. All the best

I can send an order via webhook from a restaurant ordering webapp i am using. i need an android mobile app, that once it receives the webhook, it makes a continued sound until accepted or rejected, displays buttons ACCEPT/REJECT, and prints the order received when accepted to a network or bluetooth printer .

...from ignition position. What I'd like is a circuit that would have an input for the constant, switched and earth - as well as a signal input from the door sensor. then output constant and switched. I'm looking to achieve the following: Allow the unit to stay on during cranking - most cars the unit won't have enough reserve power to stay on while cranking meaning it restarts, disconnecting bluetooth etc. I was thinking to use a small bank of capacitors or other solution which would keep it on for the 5secs or so of cranking - I was thinking if the box can utilise the constant wire it could charge the capacitors while the car is off/no ignition - so when it cranks the power is already there but not sure if this would cause a parasitic draw. Once the key is remove...
