Bugfix OSTC5 BT and enabling fast mode: The OSTC5 BT was operating at default speed of 115200. To enable the faster communication some init steps have been added to set speed to 460800. Having the UART enabled while the module was shut down caused problems during initialisation. To avoid these the BT UART is now initialized after the the module is powered on and deinitialized while the module is switched off.
