Thank you for the wonderful board. I can complain only about the SPI ROM software, windows programs and not very well ordered wiki. If you don’t own a Linux and Windows and USB-C on some PC/Laptop, you are not running this thing for the first time ever. Last and not least complain 99% of us customers buy this board to use it as a Headless server or router, we need clean debian minimal image and the procedure to build such from scratch. We absolutely hate “MATE X” and all graphical managers. Take a note how raspberry pi is distributing minimal raspbian. At least 5 threads on the forum’s first page about that problem.
Here comes my real problem: Telit LN940 A11 4G LTE Module I have around. I did recompile the W2 kernel included qmi_wwan patches for RAWIP added the telit “1bc7:1900”, also to option.c in usb_serial. Patched dhcp 4.3.5 with RAWIP support. If I connect the LN940 via “M.2 KeyB” => “USB 3.0” => “W2’s USB 3.0”. SIM Card inside the M.2 => USB3 converter. I have successful connection and the module works okay.
If I connect the LN940 M.2 Key B => “W2’s Key B”, the module is recognized perfectly, you can talk to it with AT commands to /dev/ttyUSB0-2, but the SIM card on the W2 board is not recognized by the LN940 M.2 module. I feel like I need to enable something either in the kernel or some GPIOs to enable SIM Card slot ? Last resort is resolder the SIM card holder or use a M.2 vertical extender with Sim Card holder ?
I tried to connect to the LN940’s AT terminal, check if I can choose different SIM slots, but only slot 0 is available and it’s not recognizing any SIM Card I have around. Please advise what is needed to get the SIM Card Slot on W2 working, not afraid of developing and testing.
My hope was to use the LN940 with hwnat to eth0, will that ever be possible or hwnat can only work between ETH interfaces ?
Best Regards and keep up the good work.
