Telit Modules with Super SIM
Cellular modules covered on this page
General getting started information
Please refer to the main Knowlegdebase page for modem-independent configuration tips.
Super SIM does not support NB-IoT.
Initialization
Only configure the modem’s Radio Access Technology (RAT) preference for Cat-M1. To do so, issue AT#WS46=0
.
A parameter of 2 instead of 0 indicates both Cat-M1 and NB-IoT. Do not select 1 (NB-IoT only). The default is 0.
Bring up a data connection
- Set the APN:
AT+CGDCONT=1,"IP","super"
. - Activate a PDP context:
AT#SGACT=1,1
.- This will yield the IP address.
Perform a ping
To perform a ping to a remote host after bringing up a connection as described above, issue AT#PING="8.8.8.8"
. This will yield:
#PING: 01,"8.8.8.8",2,109
#PING: 02,"8.8.8.8",1,109
#PING: 03,"8.8.8.8",1,109
#PING: 04,"8.8.8.8",1,109
OK
Perform an HTTP GET
- Set the target server:
AT#HTTPCFG=0,"jsonplaceholder.typicode.com"
.0
is the HTTP “profile ID”.
- GET a resource:
AT#HTTPQRY=0,0,"/todos/1"
.- The first parameter is the profile ID.
- The second
0
is the command:0
=GET
. - The string is the path to the required resource.
- The modem will issue an outcome URC:
#HTTPRING: 0,200,"application/json",83
.- The first parameter is the profile ID.
- The second parameter is the HTTP status code.
- The final parameter is the number of received bytes.
- The first parameter is the profile ID.
- Read the data:
AT#HTTPRCV=0,0
.- The first parameter is the profile ID.
- The second parameter is the number of bytes to read:
0
= all.
- The modem will return the data:
<<<{ "userId": 1, "id": 1, "title": "delectus aut autem", "completed": false }
Data-centric attach mode
To set the ME910C1 to force data-centric attachment, issue AT+CEMODE=2
.
The parameter’s value is as follows:
0
= PS mode 2: EPS only, data centric1
= CS/PS mode 1: voice centric2
= CS/PS mode 2: data centric3
= PS mode 1: EPS only, voice centric
This setting is non-volatile.
Low-power modes
The ME910C1 supports the eDRX and PSM low-power modes. The commands to enable each of these are:
- eDRX:
AT+CEDRXS
(see alsoAT#CEDRXS
for “extended eDRX settings”). - PSM:
AT+CPSMS
Using these features, but especially PSM, can make the modem inaccessible to the terminal during its sleep time. It’s best to experiment with these features with the modem local. To disable all power saving, send:
AT+CEDRXS=0
AT+CPSMS=0
You can learn more about implementing these modes in our low-power usage documentation.
