Hello all,
I'm currently have difficulty with an EEM applet for finding and selecting the best cellular provider. Ideally I want to store the RSSI of varying carriers as variables, then do a comparison to see which has the lowest value to action. (In place of true roaming due to a SIM preferred network list)
A snippet of the applet:
action 2.5 cli command "show cellular 0 Network"
action 2.6 regexp "MCC = 234, MNC = 33" "$_cli_result" _match
action 2.7 if $_regexp_result eq "1"
action 2.8 cli command "cellular 0 gsm plmn select manual 234 33"
action 2.9 syslog msg "Selection Successful"
action 3.0 wait 60
action 3.2 cli command "show cellular 0 all | inc Current RSSI"
action 3.3 regexp "Current RSSI = (-[0-9]+) dBm" "$_cli_result" _match net1dBm
action 3.4 set NET1RSSI "$net1dBm"
Is it possible to repeat this process storing all of the RSSI values as variables, then comparing all of those variables using some form of "if $Variable1 le $Variable2, $Varible3 then cellular 0 gsm plmn select manual XXX XX"
Many thanks in advance!

Here is an EEM TCL file that does the plmn search and chooses the best network based on RSSI. Output looks like this:

yes afaik it should be ok to do that.

Hi Daniel,
I have sent you a PM
Kind Regards.

I don't understand. You're already storing the current RSSI as a variable. The MCC and MNC numbers appear to be magic, but they could easily come from other variables. It would be helpful if you presented at least some more pseudo code of what you're trying to accomplish.

Hi Joe,
This has now been resolved.
