a. Issue following command to your cellular radio module to configure socket connection settings:
AT#SCFG=1,3,300,90,600,50
b. If data APN has not previously been programmed, issue the following command:
AT+CGDCONT=3,"IPV4V6","CorrectAPNForAccount"
If the data APN has been previously programmed, go to Step 4.c.
c. Issue the following command to check for signal presence:
AT+CSQ
d. Issue the following command to check for registration presence:
AT+CEREG?
e. If signal and registration are present, issue the following command to establish data connection:
AT#SGACT=3,1
If signal and registration are not present, check antenna for proper connection and SIM for correct
orientation.
f. Issue following command to create FTP session:
AT#FTPOPEN="204.26.122.49","username","password",1,3
g. Have the host application issue the following command to download the firmwarecheck.csv file, read
its contents, and take actions based on those contents:
AT#FTPGET="firmwarecheck.csv
h. Have host system issue the following command to Telit radio module to determine current firmware
file version and firmware build:
AT+GMR
AT#CFVR
i. If version/build indicated in responses are the same as indicated in firmwarecheck.csv: Go to Step
4.s.
j. If current firmware version is older than version indicated in firmwarecheck.csv: Continue to next
step.
k. Issue the following command to Telit radio module to download the file indicated in the
firmwarecheck.csv file and wait for OK response (which indicates the file has been downloaded):
AT#FTPGETOTA="Name-Of-Firmware-File-Here.bin",0
l. After file is downloaded issue following command to close FTP session:
AT#FTPCLOSE
m. After closing FTP, issue following command to disconnect data session:
AT#SGACT=3,0
n. After closing data session, issue following command to apply downloaded file:
AT#OTAUP=0
o. Before continuing, wait for your cellular radio to reset a total of three times and/or wait a fixed
period of time to ensure module has enough time to apply downloaded firmware. The time needed
varies depending on the size of your firmware file.
p. Issue the following command to determine current firmware version.
