We are making a product with a BLUNO as a master. We need it to connect and communicate with an external product, with BLE services (documentation provided, and hardware paid by us). The goal is to develop a library allowing us to : - discover the device - connect to the device - read notification from BLE device - write to BLE device - read from BLE device

IOS Swift app using CoreLocation Framework to interact with bluetooth BLE beacons. Very simple. Wireframe is attached. When phone gets in "Immediate" range of beacon, a local notification pops up. Opening the notification launches the app. The app sends an http request to a url with the major and minor number of the beacon it has found. This returns a particular png into the UIImageView. If the app is launched independently, a placeholder image is used until the beacon comes into immediate range at which point the same request is made and the source is updated to the response from the request. The UIImageView can be dragged with 1 finger and scaled/rotated with 2 fingers. When the capture button is pressed, the preview frame freezes and 3 buttons replace the capture button on the bottom - download, share, and retake. download and share take a retina screenshot of the frozen camera preview with the watermark. Retake restarts the camera preview and switches back to the capture button...

I am looking for someone who can build our second prototype. We need a screen that can be easily visible in direct sunlight, bluetooth technology to talk to our mobile app for screen to display things, and a magnetic backing for the device to magnetically attach to something. All needs to be weather-proof because this device is meant for outside use, so perhaps a protective casing around device that will not inhibit the visibility of what will be displayed on the screen.

Hey Guys, I have designed a circuit.The proposed circuit, will be used for a tracking device. The device can be connected to smartphone via Bluetooth protocol. This circuit contain following sections: 1. controller: This Section contains NRF51422 microcontroller, Antenna, motor driver, LED controller. 2. Power Section: This circuit provide energy for the system. This circuit also charges a battery by solar cell. The system has 2 source of energy, rechargeable battery and a backup battery. Also rechargeable battery has an output to a USB charger. 3. GSM/GPS: this circuit can locate the device and send its data through SMS to the user, also user can communicate with device in long distances via SMS. Concerns: -Circuit Size. Since the device is really compact, size of the circuit is an important factor. -Energy Efficiency: Solar cell is the only source of energy, therefore developing a low powered system is the must. Cooperation I will provide schematic design of the...
