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?
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. http://wiki.seeedstudio.com/LTE_Cat_1_Pi_HAT/#faq. 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
Note
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.
I have the similar issue as Rafal. I have the European version of the U-blox Lara R211 and when trying to connect it with RPi 2 model B according to the manual, I only receive the ‘infinite’ waking up.
I successfully managed to connect to the Telekom’s LTE network and to ping google with the help of Windows and the M-Center though, so the LTE device is operational.
My questions might be somewhat dumb, but I just wanna make sure that I am doing everything right:
In the wiki manual, it is not specifically stated how do you guys connect the LTE module to the RPi. Do you imply connection via USB or UART?
When I connected to the Telekom’s LTE network via M-Center and Windows, I used the Telekom’s Sim-Card and it had a Pin-Code, which I had to input to the GUI in order to access the network. Could it be the reason why Rpi cannot wake the modem up?
So, as I mentioned before, I have the RPi 2 Model B V1.1. However, the demo was performed at RPi 3 Model B. Could it be a compatibility issue somehow?
