Cat-M1, NB-IoT
Super SIM does not support NB-IoT.
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), and we strongly recommend you avoid 2
in order to prevent the modem from attempting to connect to NB-IoT networks if any are nearby. Such attempts will always be unsuccessful. The default value is 0.
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 centric
1
= CS/PS mode 1: voice centric
2
= CS/PS mode 2: data centric
3
= PS mode 1: EPS only, voice centric
This setting is non-volatile.
Set the APN: AT+CGDCONT=1,"IP","super"
.
Activate a PDP context: AT#SGACT=1,1
.
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:
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 request method: 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.
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:
The ME910C1 supports the eDRX and PSM low-power modes. The commands to enable each of these are:
See also AT#CEDRXS
in the ME910C1 Series AT Command Manual for extended eDRX settings, and AT#CPSMS
for further Power Saving Mode settings.
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 locally. To disable all power saving, send:
None at this time.
