Two days ago I installed OVMS in a 2017 Leaf. Usage over wifi (both AP and client) works as expected, but I'm having trouble with Hologram SIM data throughput. The Hologram site shows "connected" (blue), but not "live" (green) with 0 data throughput. Cellular and GPS antennas attached.
Only side-note is that I have NOT disconnected TCU yet. I would think this wouldn't impact the cellular link from OVMS module, but I'm a newbie.
On the OVMS web status, I get this from the cellular modem panel:
MODEM Status Model: SIM7600
Network Registration: DeniedRegistration
Provider: USCellular Hologram
Signal: -77 dBm
Mode:
State: NetWait
Mux: Status up
PPP: Not running
GPS: Connected on channel: #1
If you're not getting any data transmitted, then something is wrong with your modem config; you shouldn't get a "DeniedRegistration" message.
I recommend removing the module from your car (along with the wireless antenna) and try connecting "stand-alone". That way you can check/modify the modem config verify the cellular signal (although -77 dBm should be sufficient).
from the "edge" area
Thanks, I've loaded the edge 3.3 from 2/20/2022
Put the SIM in an unlocked “all carriers” Moto android phone. Sees T-Mobile, Hologram site shows “connected”, no data. I need to work this as a hologram problem. Could also be weak signal and initial registration falters (-77 to -85 dBm), but not as likely
it Found AT&T instead of USCellular, now working. I did not get to the level of AT commands to force find alternate carriers, but it appears to have done that on its own (recall that I put the SIM in an android phone that saw T-mobile). I will follow up in this same thread with updates.
Any follow up here? My problems are very similar and intermittent. Still having trouble or is it fixed now?
Only worked twice. I have since tried a series of AT commands without any evidence they are getting through. That could just be syntax. My plan is to dig a little deeper week after next (currently traveling/working)
Subbing for a solution to this as well. Exact same problems. New install on 4/1.
March 28th was the last time I was able to get any connection hologram.
Only Wifi is working. Solar Flare maybe?
Is there a way to force it to transmit while at home (while hooked up to wifi)?
It was a solar flare;

Everything works normal now.
Mine seemed to sort itself out. I think for me it was an antenna placement issue. Once I moved it, it connected and has been working fine ever since.
Whats your signal strength?
Network Registration: RegisteredRoaming
Provider: AT&T Hologram
Signal: -51 dBm
Mode: LTE, Online
State: NetMode
Mux: Status up
PPP: Connected channel #2
GPS: Connected channel #1
