大家说如果对讲机支持蓝牙耳机,是不是可以通过蓝牙耳机的信道将APRS信号发送到安卓手机里,然后使用Aprsdroid进行音频解码,这样就可以完美支持APRS了? 这样对讲机只要支持蓝牙音频功能,而不需要增加APRS解码芯片,是不是成本也不会很高?
摩托p8668支持蓝牙音频,谁有这机器,试试呗?
Aprsroid帮助里提到: AFSK via Speaker/Mic
You can connect an audio cable (or a bluetooth headset) to your radio transceiver. APRSdroid will modulate its packets directly via AFSK and decode incoming transmissions.
The High-Quality Demodulator is based on javAX25 by Sivan, 4X6IZ and requires Android 2.2 and a modern CPU to operate. However, it provides a significant boost in decoding quality and allows to use a Bluetooth headset.
Set the Frame Sync Prefix in [ms] to fine-tune your VOX control. AFSK output is on the left channel. Be sure to turn off ring tones and notifications from your phone/tablet to keep them from being transmitted inadvertently. 这有一个问题,这里提到蓝牙耳机,应该是说蓝牙耳机和安卓手机配对。那么支持蓝牙耳机的对讲机,对讲机也是和蓝牙耳机配对。而并非是蓝牙对讲机可以作为一个蓝牙耳机和安卓手机连接,这个可能是一个问题。
