FT (Flow Control Threshold) Command
GD (Receive Good Count) Command
HP (Hopping Channel) Command
Command Summary Description
AT Command: ATFT <Serial Interfacing> Flow Control
Threshold - Set or read flow control
threshold. De-assert CTS and/or send
XOFF when FT bytes are in the UART
receive buffer. Re-assert CTS when less
than FT - 16 bytes are in the UART receive
buffer.
Binary Command: 0x24 (36 decimal)
Parameter Range:0 – (DI buffer size minus
0x11 bytes)
Default Parameter Value: DI Buffer size
minus 0x11 (17 decimal)
Number of bytes returned: 2
Minimum Firmware Version Required:
4.27B
Command Summary Description
AT Command: ATGD
Binary Command: 0x10 (16 decimal) <Diagnostics> Set/Read the count of
good received RF packets. Parameter
value is reset to 0 after every reset and is
not non-volatile (Value does not
persist in the module’s memory after a
power-up sequence). Once the
“Receive Good Count” reaches its
maximum value (up to 0xFFFF), it
remains at its maximum count value until
the maximum count value is
manually changed or the module is reset.
Parameter Range:0 – 0xFFFF
Default Parameter Value: 0
Number of bytes returned: 2
Related Commands: ER (Receive Error
Count)
Command Summary Description
AT Command: ATHP
<Networking> HP Command is used to
set the module’s hopping channel
number. A channel is one of three layers
of addressing available to the
module. In order for modules to
communicate with each other, the
modules must have the same channel
number since each network uses a
different hopping sequence. Different
channels can be used to prevent
modules in one network from listening
to transmissions of another.
Binary Command: 0x11 (17 decimal)
Parameter Range:0 – 6
Default Parameter Value: 0
Number of bytes returned: 1
Related Commands: DT (Destination
Address), ID (Module VID), MK (Address
Mask)
