reading

usage: ebyte.py read [-h] serial pin_m0 pin_m1 pin_aux

positional arguments:
  serial      Path to the serial port device.
  pin_m0      M0 GPIO pin number.
  pin_m1      M1 GPIO pin number.
  pin_aux     AUX GPIO pin number.

optional arguments:
  -h, --help  show this help message and exit


python ebyte.py read /dev/serial0 27 17 22

Version:
--------
Frequency: 868MHz
  Version: 13
 Features: 20

Address/channel:
----------------
    addh: 0x00
    addl: 0x02
 address: 0x0002
    chan: 0x02

sped:
-----
    parity_bit: 8N1 (0)
     uart_baud: 19200 (3)
 air_data_rate: 2.4k (2)

option:
-------
  transmission_mode: fixed (1)
      io_drive_mode: TXD, RXD and AUX open-collector (1)
       wake_up_time: 250ms (0)
         fec_switch: on (1)
 transmission_power: 30dBm (0)

writing

python ebyte.py write /dev/serial0 27 17 22 --fec_switch=1 --chan=15

factory reset

python ebyte.py reset /dev/serial0 27 17 22

use as library

See the code in test_raspberrypi.py if you want to use the library in your own code. If you write to the serial device, just call ebyte.wait_for_aux_pin() after every write. You can omit the AUX_PIN parameter, a delay is then used instead of waiting for the pin to go high.

what should i do for it?

Line 165 - ebyte.py - raise UserWarning(f'not a valid property: {err}')

Not sure if this is me, I cloned your repository and before I make any adjustments (my pins are different [M0=22, M1=27 for the E22 based waveshare SX126x based LoRa hats.
SX1268_433M_LoRa_HAT https://www.waveshare.com/wiki/SX1268_433M_LoRa_HAT

I tried to run the command with anything (see paste below --help) and I get an error.

$ python ebyte.py --help
File "ebyte.py", line 165
raise UserWarning(f'not a valid property: {err}')

SyntaxError: invalid syntax

wondered if it was a permissions thing.... seems no

$ sudo python ebyte.py --help
