3.3.4 working frequency
Module data transmission frequency, different hardware modules
can work different frequency bands, roughly divided into low
frequency band (525MHz below) and high frequency band
(525MHz above) two categories.Typical operating frequency band
is 410M ~ 441MHz, 470M ~ 510MHz, 850 ~ 950MHz, etc.,
1000KHz for a channel.Different application areas have different
frequency band restrictions, as well as different channel
interference factors, the error rate is different, so need to adjust the
value according to the actual situation.
3.3.5 Air speed
The rate of data in the air can be divided into 6 levels, The higher
the level, the higher the rate. Under the same conditions, the
higher the rate, the closer the transmission distance.Therefore,
you need to adjust this value according to the actual environment.
Attention: all devices must be at the same rate, otherwise they
can not communicate.
Default: 3 Level
3.3.6 Transmitting power
The hardware module without PA can set the transmit power of 5 ~
20dBm. The power of the hardware module with PA is fixed at
30dBm.
Default: 20
