LTE CAT1 hat (Europe version)

Post by info629 » Sun Sep 02, 2018 4:49 am

I'm trying to install your LTE CAT1 hat (Europe version), but without success so far. I used the install-procedure as mentioned in the Wiki. Everything went OK, but the response is different, see attached picture. Questions:
- Why is the modem not waking up?
- Do you have any documentation on the library used to control the modem?

Hi Felix

Do you go through below 4 steps? I went through the process again. I get the response from board as below. Maybe you can connect the module to windows pc to test the AT command separately to see if it works. Here is the instructions. thanks.
Step 1. Use dtoverlay=pi3-disable-bt to enable Raspberry Pi3 UART0.

sudo nano /boot/config.txt
Then add dtoverlay=pi3-disable-bt to bottom of the config.txt

Step 2. Disable the system serivce to use the UART0.

sudo systemctl disable hciuart

Pi3-disable-bt disables the Bluetooth device and restores UART0/ttyAMA0 to GPIOs 14 and 15. It is also necessary to disable the system service that initialises the modem so it doesn't use the UART: sudo systemctl disable hciuart.

Step 3. Delete the console=serial0,115200 in cmdline.txt.

sudo nano /boot/cmdline.txt
Then delete console=serial0,115200 from the string.

Step 4. Reboot the Raspberry Pi3

sudo reboot

everything with installation worked almost first time - good!
Modem works, is booked into the LTE network, reasonable RSSI.

Now - do I actually get a network device? How do I use the LTE IP-uplink?

ip a shows only the lo, eth0 and wlan0...
