Note:
Due to the propagation characteristics of the 868/900 MHz bands, the near field effect could make that 2 modules cannot
communicate if they are placed very close (< 1 m). We suggest to keep a minimum distance of 3 or 4 meters between modules.
Regarding the energy section, the transmission power can be adjusted to several values:
Parameter
SX1272 power level
'L'
0 dBm
'H'
7 dBm
'M'
14 dBm
