Meter detection:

Performing this command deletes all the data from 2N®SmartCom PRO terminal memory as well as the meter reading configuration part. The parameter interval is global for all installed meters by AT command.

AT command: at^scamsadd=<port>,<protocol>,<baudrate>,<interval>,<number_of_expected_devices>

Examples:

(detection 2 meters on M-Bus, for speed 2400 Bd and interval 1 minute)

at^scamsadd=2,2,"default","1m",2

at^scamsadd=2,2,2400,"1m",2

at^scamsadd=2,"mbus","default","1m",2

at^scamsadd=2,"mbus",2400,"1m",2

possible interval for data reading from meters - values: 1M, 2M, 3M, 4M, 5M, 6M, 10M, 12M, 15M, 20M, 30M, 1H, 2H, 3H, 4H, 6H, 8H, 12H, 1D

Answer:
^SCAMSADD: <error_code>,<number_of_devices>,"<primary_address_1>,<secondary_address_1>;<primary_address_2>,<secondary_address_2>;................."
OK

Examples:

without error - 2 meters found

^SCAMSADD: 0,2,"0,08031768;1,15020416"

error - different number of meters found (only 1)

^SCAMSADD: 65286,1,"0,08031768"

error(collision of secondary addresses)

^SCAMSADD: 131094,0,""
