For information: Problem already encountered by moment on previous Vitugo version
the problem may be HT Tacx Flow.
Connection ensured with the PC by a TACX ANT + T2028 USB Antenna positioned near the HT.
Session failed on Wednesday, April 03 start of session at 19:10 (VirtuGO Over Under 2x10min Low VO2 to Low Tempo).
Thanks again to the Virtugo teams for the work done.
