Most of the Mobeye devices can be programmed by simple SMS commands. These follow a simple but strict format. Even if the format was typed in correctly and sent properly, the Mobeye device can ignore the SMS command. Most probably this has to do with the SMS settings in your mobile phone. In order to find the reason why your SMS command is rejected, please check the following:

1. Make sure that the Mobeye device is able to receive commands.

   The GSM module needs to be open and connected to the network. Please use the manual to learn how to do. If necessary, you can download the manual via our support page.

2. Make sure you format the SMS command properly.

   Most commands have the following structure: CODE SETTING:OPTION
   
   In the factory defaults the CODE is 1111.
   Next type a space.
   The option (such as DELAY1) can be written in capital letters or in lowercase.
   Next type a colon (:)
   Immediately after write the option for the setting (e.g. 99 as delay time)

3. If the correct SMS command was sent, but the unit disapproves the command (by red LEDs or a low sound), please check if the SMS settings in your telephone are set to “GSM alphabet” instead of “Unicode”.

   Check this in the following way:
   Go to the SMS messaging app.
   Open the settings for the SMS input mode.
   You can choose between “GSM alphabet”* or “Unicode” (or other). Choose GSM alphabet.
