4.2 Activating LTE Using AT Commands
Check with the CalAmp Sales team for availability of the LMU-3640™ with GSM or HSPA modems.
If you get an LMU without a SIM (which is the typical case) the operator will simply ask for the IMEI of the LMU. The IMEI (International
Mobile Equipment Identifier) is printed on the bottom of the LMU under the LMU’s ESN. Again, DO NOT give the operator the ESN of the
LMU.
The operator will provide you with a SIM for each account activated. If they are especially nice (or you are especially persistent) they will also
give you a list tying the IMSI (International Subscriber Identifier) of the SIM to the phone number assigned to it. Please note that the operator will
likely tie the IMSI (i.e. the SIM) to a specific IMEI. Making sure the specific SIM matches to the right IMEI isn’t strictly necessary, but it will
keep everyone’s book-keeping a little cleaner. You may also obtain this information by running a CSV report in PULS (after the devices have
connected to the network and sent in their first ID Report). See the PULS Users Guide for more information.
If you do happen to have a SIM, the operator will ask for the IMSI and ICC-ID (Integrated Circuit Card Identifier) along with the IMEI of the
LMU. Again, in return you should get a list of IMSIs and Phone Numbers.
The IMEI, IMSI and ICC-ID are all available through the ATI1 command. The IMEI should also be printed on the bottom of the LMU.
You should also get an APN (Access Point Name) value. The APN is the device on the network that allows a GPRS device (i.e. the LMU) to get
to the internet. They tend to look like a URL, for example:
myAPN.myOperator.com
Operators can offer more than one type of APN and can even set up a custom APN just for your devices. The rates they charge will vary
depending on the APN service you want. Operators may also request you use a blank APN. With the APN, you should also receive a username
and password combination.
The last item an operator may provide is a SIM PIN. The PIN is effectively a password to the device. The main difference here is that the PIN will
restrict all the capabilities of the device, where the SPC is used just for configuration.
The activation sequence for a HSPA LMU would therefore look as follows:
AT$APP PARAM 2306,0,“myAPN.myOperator.com”
AT$APP PARAM 2306,1,“myAPN.myOperator.com”
AT$APP PARAM 2314,0,“myUSername”
AT$APP PARAM 2315,0,“myPassword”
For a blank APN the following command can be used:
AT$APP PARAM 2306,0,“” (for a blank APN)
Only enter this next command if you have been given a non-zero PIN as any errors may lock you out of the modem.
AT$APP PIN <SIM pin>
You can confirm activation by watching the Comm LED to see if it goes solid. You may also confirm activation using
AT$APP COMM STATUS?
A good response should look similar to the following:
