I check lora_aprs code and this project use your library. LOWBITRATEOPTIMIZE (register config_3(0x26), bit 3) need to be set when symbol time is above 16ms. With BW125 SF12 for APRS, the symbol time is 32.77ms and leaving this bit at 0 may cause worse decoding and bad receiver performance. Bit must be set at both side of link.
