I am trying to develop some software for the fxt009, I am using developer studio 2.1.1 and I installed the firmware 7.46. Suddenly I can’t get normal contact with the fxt009 anymore, I try to connect via USB which was fine before. In the TMConsole I see several AT Commands pass, like WDM: 3, WOPEN: 6,1024,4096, WOPEN: 1, but then I get CME ERROR: 3 and the process of opening the port hangs at getting target information. I tried to restart my pc, restart the fxt009 reset to factory settings, but it all seems not to help anything. Are you guys familiar with such a problem? I tried to search the forum but couldn’t find anything useful yet. If I try AT+CMEE=0 I get ERROR, maybe the firmware is corrupted? The problem is that I can’t update the firmware because the studio can’t open the port fully. I hope you guys can help 😉 thanks in advance! ---
