14.28 USER_CMD
An Over-The-Air command was received. The parameter [0-255] indicates which action to take.
This is currently supported for ORBCOMM and GSM/GPRS networks.
When a USER_CMD is sent, byte 0 of the data represents how many user commands will be
sent. This is based on User Data Bytes 1-4 content in conjunction with User Byte 0’s value.
For example, using:
USER DATA BYTES 0 1 2 3 4
Example. 1: If the data bytes sent were 0x01 0xFF 0x00 0x00 0x00
• One USER_CMD event would be sent to the application.
• It would be USER_CMD 255.
• Notice that User Data Bytes 2-4 have no meaning.
Example. 2: If the data bytes sent were 0x02 0xFF 0x00 0x00 0x00
• Two USER_CMD events would be sent to the application.
• They would be USER_CMD 255 and USER_CMD 0.
• In this case User Data Bytes 3 and 4 have no meaning.
Example. 3: If the data bytes sent were 0x03 0x01 0x02 0x03 0x00
• Three USER_CMD events would be sent to the application.
• They would be USER_CMD 0, USER_CMD 1 and USER_CMD 3.
• In this case User Byte 4 has no meaning.
Example. 4: If the data bytes sent were 0x04 0x01 0x02 0x03 0x0A
• Four USER_CMD events would be sent to the application.
• They would be USER_CMD 1, USER_CMD 2, USER_CMD 3, and USER_CMD 10.
