Python 3 command line tool/library for controlling Ebyte LoRa modules like the E32 with GPIOs (Raspberry Pi).

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

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.
