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 nonvolatile
(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.
FL (Software Flow Control)
Command
<Serial Interfacing> The FL
command is used to configure
software flow control. Hardware
flow control is implemented with the
module as the GP01 pin (CTS pin
of the OEM RF module), which
regulates when serial data can be
transferred to the module.
FL Command can be used to allow
software flow control to also be
enabled. The XON character used
is 0x11 (17 decimal). The XOFF
character used is 0x13 (19 decimal)
