Hi all I'm suddenly having problems with the modem. It is stuck in PoweringOn and shows a signal of 0 dBm. Here the status: Network Registration: NotRegistered Provider: Signal: 0 dBm State: PoweringOn PPP: Not connected GPS: Not connected And here the debug log: I (201194) simcom: State timeout, transition to 2 I (201194) simcom: State: Enter PoweringOn state I (201194) simcom: Power Cycle D (201194) max7317: egpio.output.0.high D (202194) max7317: egpio.output.0.low D (202204) events: Signal(system.modem.poweringon) D (202204) events: Signal(egpio.output.0.high) D (202204) simcom: tx scmd ch=0 len=4 : AT D (202214) events: Signal(egpio.output.0.low) D (203194) simcom: tx scmd ch=0 len=4 : AT D (204194) simcom: tx scmd ch=0 len=4 : AT D (205194) simcom: tx scmd ch=0 len=4 : AT D (206194) simcom: tx scmd ch=0 len=4 : AT D (207194) simcom: tx scmd ch=0 len=4 : AT D (208194) simcom: tx scmd ch=0 len=4 : AT D (209194) simcom: tx scmd ch=0 len=4 : AT D (210194) simcom: tx scmd ch=0 len=4 : AT D (211194) simcom: tx scmd ch=0 len=4 : AT D (212194) simcom: tx scmd ch=0 len=4 : AT D (213194) simcom: tx scmd ch=0 len=4 : AT D (214194) simcom: tx scmd ch=0 len=4 : AT D (215194) simcom: tx scmd ch=0 len=4 : AT D (216194) simcom: tx scmd ch=0 len=4 : AT D (217194) simcom: tx scmd ch=0 len=4 : AT D (218194) simcom: tx scmd ch=0 len=4 : AT D (219194) simcom: tx scmd ch=0 len=4 : AT D (220194) simcom: tx scmd ch=0 len=4 : AT D (221194) simcom: tx scmd ch=0 len=4 : AT Hard reset did not help ... I found this discussion https://www.openvehicles.com/node/2381 with recent postings. Could there be a general problem with the modem, or is it my hardware (again ...)? Thanx Chris
