AT Command Response
Frame Type: 0x88
In response to an AT Command message, the module will send an AT Command Response
message. Some commands will send back multiple frames (for example, the ND (Node Discover)
command).
Example. Suppose the BD parameter is changed on the local device with a frame ID of 0x01. If
successful (parameter was valid), the above response would be received.
Modem Status
Frame Type: (0x8A)
RF module status messages are sent from the module in response to specific conditions.
Example. The following API frame is returned when an API device powers up.
Frame Fields Offset Example Description
Start Delimiter 0 0x7E
Length
MSB 1 0x00
Number of bytes between the length
and the checksum
LSB 2 0x05
Frame-specific
Data
Frame Type 3 0x88
Frame ID 4 0x01
Identifies the UART data frame being
reported. Note: If Frame ID = 0 in AT
Command Mode, no AT Command
Response will be given.
AT Command
5 ‘B’ = 0x42 Command Name - Two ASCII
characters that identify the AT
Command.
6 ‘D’ = 0x44
Command
Status
70x00
0 = OK
1 = ERROR
2 = Invalid Command
3 = Invalid Parameter
Command Data
Register data in binary format. If the
register was set, then this field is not
returned, as in this example.
Checksum 8 0xF0
0xFF - the 8 bit sum of bytes from
offset 3 to this byte.
Frame Fields Offset Example Description
Start Delimiter 0 0x7E
Length
MSB 1 0x00
Number of bytes between the length
and the checksum
LSB 2 0x02
Frame-specific
Data
Frame Type 3 0x8A
Status 4 0x00
0x00 = Hardware reset
0x01= Watchdog timer reset
0x0B = Network Woke Up
0x0C = Network Went To Sleep
Checksum 5 0x75
0xFF - the 8 bit sum of bytes from
offset 3 to this byte.
