DT (Destination Address) 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
Destination 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.
E0 (Echo Off) Command
<Command Mode Options> E0 Command turns
off character echo in AT Command Mode.
By default, echo is off.
E1 (Echo On) Command
<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.
ER (Receive Error Count) Command
<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.
FH (Force Wake-up Initializer) Command
<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.
