Подключил модуль WB-RGB Диммер RGB — Wiren Board. Все по инструкции, но почему-то модуль совсем не хочет работать.
Настройки указал следующие (wb-mqtt-serial.conf):
{
“debug”: true,
“ports”: [
{
“path”: “/dev/ttyAPP1”,
“baud_rate”: 9600,
“data_bits”: 8,
“stop_bits”: 2,
“parity”: “N”,
“enabled”: true,
“devices”: [
{
“device_type”: “WB-MRGB”,
“name”: “wb-mrgb 122”,
“id”: “wb-mrgb_122”,
“slave_id”: 122,
“enabled”: true
}
]
}
]
}
В логи выводится следующее:

При попытке запустить wb-mqtt-serial в ручную в отладочном режиме (wb-mqtt-serial -c /etc/wb-mqtt-serial.conf -d) выдает практически то же самое:
