I am working on a program that allows sending acceleration measurements from XDK to PR21. I found out that I need a supported BLE adapter, which is described in the documentation. This adapter must be installed in Linux on the PR21. I would like to know what BLE adapter is about? I heard that I need some PR21 code written in e.g. Python to connect via BLE to XDK and download data. Is anyone able to send some sample code?
the PR21 and the IoT Gateway project is mantained by Bosch Rexroth. The PR21 uses the bluez Linux service for the BLE functionality and in their documentation you can find the adapter used (LM Technologies Bluetooth® v4.0 Dual Mode Long Range USB Adapter – LM1010)
The PR21 supports the BCDS & Rexroth products CISS and SCD which have different protocols / BLE interfaces than the XDK.
For development purposes, the XDK team used BLED112 USB adapters from Bluegiga to test devices using the python libraries.
