E22-xxxT22S series product user manual
When the data sent is larger than the sub packet
length, the serial port in receiving end willsub
packet the data and then output them.
RSSI enable command (Sub packet setting,
transmit
power
as
default
configuration mode): C0 04 01 20;
After enabling, the command C0 C1 C2 C3 can be
sent in the normal mode(mode 0)
transmission mode (transmitter in mode 1) to read
the register;
Register 0x00: current environmental noise RSSI;
Register 0x01: RSSI at Last Data Received
(Current channel noise is: dBm = -(256 - RSSI));
Command
format:
C0
address+read length;
Return: C1 + address + read length + read valid
value;
For example:
Send: C0 C1 C2 C3 00 01
Return: C1 00 01 RSSI
(the address can only
start from 00)
If you use Ebyte's host computer configuration
software, this bit will be turned off
automatically.
If you don't want to use the M0
M1 pins to switch working modes, you can
enable this function, and use specific serial port
commands to switch modes.
Format: C0 C1 C2 C3 02 + working mode
Send C0 C1 C2 C3 02 00 to switch to transparent
transmission mode
Send C0 C1 C2 C3 02 01 to switch to WOR mode
Send C0 C1 C2 C3 02 02 to switch to
configuration mode
Send C0 C1 C2 C3 02 03 to switch to sleep mode
Return: C1 C2 C3 02 + working mode
Note: After enabling this function, WOR mode
and sleep mode only support 9600 baud rate.
There is a non-linear relationship between power
and current. At the maximum power, the power
supply efficiency is the highest ;
Current does not decrease in proportion to the
decrease in power.
Actual frequency = 410.125MHz + CH * 1MHz
Actual frequency = 850.125MHz + CH * 1MHz
