SurfPad: UWP Bluetooth to Bluetooth Connectivity Solved

The SurfPad project as on GitHub and hackster.io is a UWP app that runs on a touchscreen Windows device. It runs as the configurable UI for an app running on an embedded device such as an Arduiino device or a Raspberry Pi (running IoT Core).. The frontend sends single characters as commands (representing button presses) whereas the backend returns responses as text strings, representing sensor data that the remote device has determined. So the communication data is textual. The communication between the two devices can be a network sockets client-server conduit, USB Serial or Bluetooth Serial. Whilst Bluetooth Serial works OK between a Windows 10 desktop (or IoT Core) as the frontend and an Arduino device as the remote backend, using an IoT Core device as the backend has been shown to be problematic. This article presents an alternative based upon Bluetooth RFComm Chat client –server architecture, which does work.

Interconnect issue over Bluetooth Serial

Issue: Can pair a Windows 10 device with an Arduino device and communicate over RFCOMM. But although can pair two Windows 10 devices over Bluetooth Serial, I can’t serially transmit between them: No serial port for OutGoing end.

Windows 10 IoTCoreDashboard: A Slight change (Incl. Update on Remote Client)

If you are used to right clicking on a Device in My Devices to get a menu of options for connecting to your device, then this functionality has been moved to the Actions column in the current version of IoTCoreDashboard.

SurfPad: RPI as the SurfPad (Bluetooth Connectivity)

This article covers using a Raspberry Pi running a RS4 version of IoT Core as the SurfPad, withe an Arduino devices as the Remote app. Connectivity for this is via Bluetooth..

Notes on RPI Windows 10 IoT-Core WiFi & BT Connectivity

Windows 10 IoTCore, as implemented on the Raspberry Pi 2 (RPI2)  initially came with no WiFi or Bluetooth (BT) connectivity. These were then added as USB dongles but with a limited listed of hardware that worked. RPI3 has built in WiFi and BT. What is the state of play with IoTCore connectivity with the RPI now? Are there any issues?

SurfPad: SurfPad States

As part of a series of articles on a set of projects targeted at using a Windows Surface device as the presentation layer for a RPI or Arduino device, this article views the apps as state machines and documents the app states coupling through message passing between them.
