Hello,
Thank you so much for your help! With your guidance, I’ve managed to get the device recognized by the computer, which was a major step forward. It appears that pin 22 for VBUS_SENSE was key.
Now, I am trying to get the EM9191 module to work on a Raspberry Pi Compute Module 4. When connected, it’s detected by the system and I’ve succeeded in connecting to the module’s serial interface, which is great. However, I’ve run into a challenge: although I can communicate with the module and even obtain an IP address using AT commands, this address doesn’t seem to be passed on to the Raspberry Pi’s internet interface. A wwan interface is created but it remains inactive and without an IP address.
I would greatly appreciate any suggestions you might have or guidance on what steps I should take next. What should I check or adjust to ensure that the wwan interface becomes active and correctly receives IP details via DHCP?
Thank you very much for your response and for your ongoing support.
