Trying to run hologram on a Jetson Nano for PPP connectivity. I was able to get a good install by installing it on python 3.7 (the Jetson requires 3.6 so it must be in parallel).
However, the CLI is giving me a timeout:
$ sudo hologram modem signal -vv
DEBUG: checking for vid_pid: (‘12d1’, ‘1001’)
DEBUG: checking for vid_pid: (‘12d1’, ‘1506’)
DEBUG: checking for vid_pid: (‘1546’, ‘1102’)
DEBUG: checking for vid_pid: (‘1546’, ‘1104’)
DEBUG: checking for vid_pid: (‘05c6’, ‘90b2’)
INFO: Detected modem NovaM
DEBUG: checking port ttyUSB0
DEBUG: checking port ttyUSB1
INFO: opened port
DEBUG: [AT]
DEBUG: {}
INFO: Timeout
ERROR: Unable to detect a usable serial port
It’s timing out waiting for a response to the AT command. But if I use screen to connect to the ttyUSB1 port I’m able to get responses to AT commands.
I tried editing Modem.py to add in retries and boost various timeouts, but no luck. Any clue what could be amiss? Or is there a simple way to setup PPP without the hologram cli?
To keep this test simple I’m doing this with a standard Jetson Nano production module and carrier board with a Hologram Nova modem plugged into the USB hub.
