9 Using a Pre-Pay SIM Card
The current version has no special feature for pre-pay SIM cards - it is up to the user to
ensure the account is kept in credit and that the SIM is used frequently enough to keep the
account active with the service provider.
Most service providers allow the account to be registered online and the account balance to
be checked from a webpage. Topping up can be performed by phone, online, in most shops
and at most ATMs.
The MesCom can be configured to send a routine text message to ensure the SIM is kept
active.
The example below will send a text message with the board temperature every 7days at
10am
9876 OPTION LOGINT 10800 SYNC 600
9876 POINT Temperature LOG yes
10 Using a Roaming SIM Card (TIME not set)
The MesCom will work with roaming SIM cards. When using a roaming SIM, the radio
module is unable to get the time in a suitable format so the MesCom is unable to determine
the current time from the GSM network The MesCom will attempt to get the current time
from other sources. If this fails the default power up date is 1
st
January 2000 - the user can
change this with the OPTION TIME command.
Example:
9876 OPTION TIME 25/07/13,17:52:12+0100
11 Using Web Based Data Concentration Services eg Xively
The MesCom has limited support for services such as Xively (aka Cosm or Pachube),
Nimbits etc. Please contact Dycon for more details.
12 FTP Upload
The MesCom can use FTP in 2 ways to allow you to see the status of your MesCom via a
remote server. Please contact Dycon for more details.
12.1 Remote Event log
The MesCom can be configured to create a list, on a remote FTP server, of all events that
occur in the MesCom. The remote server could be configured to allow this file to be viewed
from a web page or imported into spread-sheet program (eg. Excel).
12.2 Remote status page
The MesCom can be configured to create a simple status file on a remote FTP server in
plain text or HTML format. The remote server would have to be configured to allow this file to
be accessed from a web browser on another computer.
