E220-900T30D

[cafalchio]

Hi, I have tried example code on the e220 900T30D using the esp32 Expressif v4 kit.

from lora_e220 import LoRaE220
from machine import UART

uart2 = UART(2)
lora = LoRaE220('900T30D', uart2, aux_pin=15, m0_pin=21, m1_pin=19)

code = lora.begin()
print("Initialization: {}", ResponseStatusCode.get_description(code))

I am getting the following error: Any Idea how to solve?
Traceback (most recent call last):
File "", line 7, in
File "/lib/lora_e220.py", line 350, in begin
OSError: (-258, 'ESP_ERR_INVALID_ARG')
