Add support for the new OSTC hardware

Browse source 
In the latest OSTC hardware, the Telit/Stollman bluetooth module has
been replaced with a u-Blox Nina B2 bluetooth module. The BLE
communication protocol remains roughly the same, except for a few minor
differences:

 - New UUIDs for services and characteristics
 - Only one common characteristic for Rx and Tx
 - Credit based flow control is optional
 - Credit value of 255 corresponds to a disconnect
