Which will then start boot zephyr os and the 8e host example. Then we can run the 80 plus c. Fund. Which sets the functional mode or actually asks what the functional mode is we can see that it returns.
Four and that means that it s in offline mode. And when we get that response. We it automatically sets the functional mode to 1. Which means normal mode.
Then we can run the command. One more time to get a bit more data. We also notice that here in the right corner the modem and the uic see that they turned green lte. It s currently closed.
But it takes a while and soon it ll turn to yellow which means it will be searching and then after a while it will turn to green which means we should have a connection and then you have the packet domain. Which is currently turned off so we can go through some of the commands quickly this command here the 80 plus c. Gsn. That s a very useful command.
If you want to figure out the e m. The i code or the imei code on the back of the dev kit. You can also the cg mm. Which will request the model id.
