E0 (Echo Off) Command
E0
Command turns off character
echo in AT Command Mode.
By default, echo is off.
E1 (Echo On) Command
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
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
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
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)
