BI2SC According to the information from the colleague at the higher level, it seems that Direwolf can only forward data packets originating from "is", but only if they are message-type packets and the destination callsign was recently received by the current igate via radio. In other words, it will not forward beacon-type packets.
Although I haven't been able to test it thoroughly... My location is too far from the digipeater, making it difficult to connect. Therefore, setting up my own gateway is quite challenging.
Furthermore, when using a direwolf to connect to the handheld radio and perform igating, it is best to use an audio cable with PTT control (do not use vox because it may cause the transmission to end prematurely while the transmitter remains active, which can occupy the frequency). Since the Raspberry Pi does not have audio input ports, you will also need a USB sound card.
