DT (Destination Address) Command
E0 (Echo Off) Command
E1 (Echo On) Command
ER (Receive Error Count) Command
FH (Force Wake-up Initializer) Command
<Networking & Security> DT Command is used to
set/read the networking address of an RF module.
The modules utilize three filtration layers: Vendor
ID Number (ATID), Channel (ATHP), and Destina-
tion Address (ATDT). The DT command assigns an
address to a radio that enables it to communicate
with other radios in the network. The simplest use
of this command is that when MY=0xFFFF and
MK=0xFFFF on all radios in a network, only radios
with matching DT's will communicate with each
other.
If MY is not 0xFFFF, then DT acts as a transmit address and MY acts as a receive address. For
example, MY can be set to unique values 1, 2, 3, etc. on unique radios in the network. Then set DT
on the transmitting radio to match the MY of the receiving radio you intend to communicate with.
Setting DT=0xFFFF will broadcast to all radios in the network. Refer to the 'Addressing' section
[p45] for more information.
<Command Mode Options> E0 Command turns
off character echo in AT Command Mode.
By default, echo is off.
<Command Mode Options> E1 Command enables
character echo in AT Command Mode. Each typed
character will be echoed back to the terminal
when ATE1 is active. E0 (Echo Off) is the default.
<Diagnostics> The ER command is used to set/
read the number of receive-errors. The error
count records the number of packets partially
received then aborted on a reception error. This
value returns to 0 after a reset and is not non-
volatile (Value does not persist in the module's
memory after a power-up sequence). Once the
Receive Error Count reaches its maximum value
(up to 0xFFFF), it remains at its maximum count
value until the maximum count value is explicitly changed or the module is reset.
The ER parameter is not reset by pin, serial port or cyclic sleep modes.
<Sleep (Low Power)> The FH command is used
to force a Wake-up Initializer to be sent on the
next transmission. Use only with cyclic sleep
modes active on remote modules. 
ATFH will not send a long header if ATHT = 0xFFFF. WR (Write) Command does not need to be
issued with FH Command.
