What firmware version do you have on the SIMCOM?
The one that most recently wedged is... wedged again: OVMS# simcom cmd AT+CGMR ERROR: SIMCOM command channel not available! But in a new way, the gps is working and the modem is registered with the network: OVMS# simcom Network Registration: RegisteredRoaming Provider: T-Mobile Hologram Signal: -93 dBm State: PoweringOn PPP: Not connected Last Error: User Interrupt GPS: Not connected I guess it got into a funny state when I was driving earlier. Anyway after rebooting it was still stuck in PoweringOn so I cycled power. Ok, both of the modules I have in cars are 35316B07SIM5360A. My third module is the one I swapped simcoms in and is LE11B02SIM7500A (physical label says 7600A). I registered with techship.com and have the firmware update tool. But the only rar files I see look like they're for the European SIM5360? https://simcom.ee/documents/?dir=SIM5360 35316B09SIM5360E.rar 35316B10SIM5360E.rar 35316B10SIM5360E_QDL5.1.rar and I don't see anything for the 7600. I've asked if the US firmware is available. What's the path to upgrading simcom firmware? Is it just a matter of plugging the usb connector on the modem board to my windows 10 laptop? I can see USB_D- and USB_D+ connections to the simcom, not sure about USB_5V. Tomorrow I'll try to pull my car modules and determine if the modem boards have the pullup resistor or not. One last thing I'm confused about is the pullup resistor on the MEM_EN line. I don't see it on v3.1 or v3.2 schematics? I tried to complare the pdfs from github visually and the only difference I see is in the A0Z1280CI circuit (and I remember Mark saying they added a choke to the power supply). Craig
