Start m-center. Connect to SARA-R5 and start an AT command terminal from m-center on the
VCP associated with interface 1.
9.
m-center terminal:
reset NVM to factory defaults
AT+UFACTORY=0,2
10.
NORA-B1 terminal:
activate reset by power cycling SARA-R5 with
modules SARAR5 power_off
modules SARAR5 power_on
11.
m-center terminal:
disable RF activity
AT+CFUN=0
12.
m-center terminal:
register with carrier
AT+CEREG=2;+CGEREP=1,1
AT+CGDCONT?
AT+CGDCONT=1,

Step 13 may take several minutes since global scanning is enabled
14.
m-center terminal:
activate registration
AT+CGREG=2
AT+CGREG?
AT+CEREG?
15.
m-center terminal:
wait for:
+CGREG: n,5

or
–
+CEREG: n,5
16.
m-center terminal:
check for AT+CGATT completion
AT+CGATT?
17.
m-center terminal:
check automatic activation
17.1.
If
AT+CGATT?
Above returned
+CGATT: 0
then activate explicitly.
17.2.
DO NOT do this STEP if
+CGATT: 1
was returned.
AT+CGATT=1
AT+CGATT?
18.
m-center terminal:
check activation
AT+CGACT?
19.
m-center terminal:
activate explicitly only if needed
19.1.
If
AT+CGACT?
Above returned
+CGACT: x,0
then activate explicitly
19.2.
DO NOT do this STEP if
+CGACT: x,1
was returned.
This is for GPRS. For LTE this should not be required.
AT+CGACT=1
AT+CGACT?
20.
m-center terminal:
set same context type (IPV4) for internal context as reported in
+CGDCONT
when the module radio is OFF
(+CFUN=0)
AT+UPSD=0,0,0
21.
m-center terminal:
map the existing external context on
<cid>=1
configuration to the internal
context on
<profile>=0
AT+UPSD=0,100,1
22.
m-center terminal:
activate the internal context on
<profile>=0
AT+UPSDA=0,3
23.
m-center terminal:
if
AT+UPSDA=0,3
above failed then de-activate context & retry
23.1.
De-activate the PDP context associated with profile zero
AT+UPSDA=0,4
23.2.
Now repeat from STEP 20.
24.
m-center terminal:
obtain socket number
AT+USOCR=17
24.1.
The
AT+USOCR=17
above will return
+USOCR: <N>
where
<N>
is the socket number.
25.
m-center terminal:
enable the secondary UART on SARA-R5
AT+USIO=2
