mPack AutoTCP use case

AT#SERIAL=(baud),(char_framing),(flow_ctrl)

• baud: 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200.
  
• char_framing: "8N1", "8N2", "9O1", "9E1"
  
• flow_ctrl:
  
• 1 = disable
  
• 2 = enable
  

Set APN

AT#IPCELLULAR=1,"soracom.io","sora","sora",1

AT#IPCELLULAR=1,(APN),(username),(password),(cid)

• APN: max 64 char, in quotes
  
• username: max 25 char, in quotes. If unspecified, "*" is assumed.
  
• password: max 25 char, in quotes. If unspecified, "*" is assumed.
  
• cid
  

Set TCP server IP and port

AT#IPTCP=1,60000,"C","162.242.170.49"

AT#IPTCP=(idx),(port),(mode),(ip)

• idx:
  
• 1 = RS-232 port
  
• 2 =  USB port
  
• port: from 0 to 65535
  
• mode:
  
• "C" = Modem as client to remote server
  
• "S" = Modem as server for remote client to connect
  
• ip: IP address of the remote partner (IPv4 dotted notation)
  
  

Set automatic TCP connection

AT#AUTOTCP=1

• mode:
  
• 0 = AUTOTCP connection OFF
  
• 1 = AUTOTCP connection ON
  

Test case

Use IPPING along AUTOTCP to ensure the connection is steady and available at all time

step1: Configure ping using "AT#IPOPT" command

• option:
  
• 0,1 = (reserved)
  
• 2 = configure ping address and parameters
  
• address: IP address of the target to be pinged. Can be set as an IPv4 format (xxx.xxx.xxx.xxx) or as a dom URL (i.e. domain.com)
  
• num: numbers of ping trials for each ping action. Default value is 3.  Valid range is 1 to 10.
  
• interval: time in seconds between each ping trial. Default value is 3.  Valid range is 1 to 10.
  
• timeout: time in ms before ping is timed out. Default value is 10. Valid range is 5000 to 60000.
  

step2: enable periodic ping

• time_period: time in seconds between 1 to 65535. If 0 ping is disabled.
  
• action: specify the actions to be taken if ping is failing
  
• 0 nothing
  
• 1 disconnect the data connectivity, and let AUTOTCP reinitiate the link.
  
• 2 reset the mPack.
