E95-DTU(433Cxx-485)-V2.0 User manual
*
Only for general transmission
mode;
* When enabled, the command "C0
C1 C2 C3" can be sent to read
the
registers
in
transmission mode: register
[0x00]: current ambient noise
RSSI[0];
register
RSSI[1] at the last received
data;
* Conversion formula: dBm =
RSSI/2-146;
* Instruction format analysis:
Send: C0 C1 C2 C3 + start
address + read length; Return:
C1 + address + read length +
read RMS value; [Example 1]:
Send C0 C1 C2 C3 00 01, return
C1 00 01 RSSI[0]; [Example 2]:
Send C0 C1 C2 C3 00 02, return
C1 00 02 RSSI[0] RSSI[1]; [].
Special Note] The address can
only start from 0x00, if you
need to read RSSI[1], you can
only refer to [Example 2]; if
the radio never receives data,
the default value of RSSI[1] is
0x00.
* Turning on Speed Priority
reduces the data output delay
at the receiving end by about
60%, but affects the receiving
distance. For example, in
115200 baud rate continuous
transmission mode, the
receiver side can output the
first frame data from the
transmitter side after 3ms.
* At 230400 baud rate, only
distance priority is
supported.
*
Power
and
current
non-linearly related, and the
power supply is most efficient
at maximum power;
* Current does not decrease in
the same proportion as power
decreases.
* Actual frequency = 410MHz + CH
* 0.5MHz, default 433MHz =
[0x2E].
* Value range: 410MHz ~ 441MHz,
[0x00] ~ [0x3E].
