I have configured four slave nodes, but it takes many times to run a2bapp to detect the node. Most of the time, the node cannot be detected. When it cannot be detected, the following error occurs: [pal_log. c: 328]: 87 discovery c:a2b_ OnDiscTimeout (1099) [ERROR] A2B Master Plugin onDiscTimeout (): DISCOVERY, what causes this, and how can I modify it? My bus may be 6 meters long
