Hi list, I am trying to play with the interactive mode and communicate to a fitbit flex tracker. > c ; d ; l ; tx 1 ; al > => c0 10 03 > <= I do get the expected "start of dump" response However, I am unable to get the next packets (minidump, and end of dump) > <= And afterwards, whatever command I issue, c0 05, c0 09, c0 12... I get no data in the response. What's happening? Any idea? Regards Axelle
