change pins for the HAB pi board on CE1:
class BOARD:
# Note that the BCOM numbering for the GPIOs is
used.
DIO0 = 16 # RaspPi
GPIO 16 = wpi 27 = phys 36 (input)#dio0 on habboard
# DIO1 = 12 # RaspPi GPIO 12
= wpi 26 = phys 16 (input)DIO5 on habboard
# DIO2 = 24 # RaspPi GPIO 24
= wpi 5 = phys 18 (input)#notused
# DIO3 = 25 # RaspPi GPIO 25
= wpi 6 = phys 22 (input)#notused
LED = 13 # RaspPi
GPIO 23 = wpi 1 = phys 33 ( make output on ‘internet’ LED)

change the default= items in the __init__ self section to
the required frequency, spreading factor,bandwidth etc that you are using.
Setting them here for 433MHz board means constructing a LoRa object without all
the parameters will at least work without defaulting to 868mhz. I have mine set
at 434.4mhz
#####################
pySX127x/SX127x/LoRa.py
Line 84 change calibration freq to 433mhz
Line 815 change freq to 433mhz
This just allows the self-test facility to work at 433mhz
without supplying further parameters
remove any initialisations for DIO2 onwards
################
you can now run pySX127x/test_lora.py, to see if
it works. Do a ‘gpio readall’( part of wiringpi) beforehand, which seems to
un-stick it – I guess some wiring pi is not being initialised completely….

I have a blind receiver running continuously, so I just
modify the file pySX127x/rx_cont.py:
Line 44: in function
def on_rx_done(self):
this is where I add my code – and is triggered on each
successful packet reception:IO
