Hello,
I am using an EC200U-EU modem with my Jetson Orin Nano. Previously, I was able to get it working on Ubuntu 20.04 by following the attached document’s configuration steps. However, after upgrading the kernel and Ubuntu versions, I am unable to establish a PPP connection, although the SIM card and network are detected.
Here are the relevant details:
- Kernel Version: 5.15.136-tegra
- Modules Loaded: cdc_ether, option (rndis_host not loaded)
AT Commands:
- AT → RDY OK
- AT+CPIN? → +CPIN: READY
- AT+CGDCONT=1,“IP”,“internet” → OK
- AT+CFUN=1 → OK
- AT+CGATT=1 → OK
- ATD*99# → CONNECT
Despite the “CONNECT” message, no connection is established.
I have attached the ModemManager logs for reference. Additionally, I have not modified the serial and wwan files in the kernel.
Any assistance on how to adapt the configuration to the new kernel would be greatly appreciated.
I also want to be able to run it smoothly with the modem manager at the end of the day.
Thank you!
