请问下，回调只收到部分数据怎么解？ #30

Open phoebewow opened 2 years ago

看日志数据是全部接收到了的，但是回调只给了部分

D/BluetoothGatt: onNotify() - Device=50:33:8B::: handle=21 D/EasyBLE: characteristic change! [UUID: 0000f1f2, addr: 50:33:8B:21:C3:5B, value: A5 07 10 00 00 20 20 30 31 2D 30 30 2E 32 2E 30 31 20 20 20] D/BluetoothGatt: onNotify() - Device=50:33:8B::: handle=21 D/EasyBLE: characteristic change! [UUID: 0000f1f2, addr: 50:33:8B:21:C3:5B, value: 20 1C BD 5A]

这个数据，第一条的数据有回调，第二条数据就没有 是因为这两条数据连发的原因吗？

wandersnail commented 2 years ago

都会回的呀

phoebewow commented 2 years ago

确实是只收到了一条数据 这两条数据下位机那边实际发送的是一条，共24个字节，但是蓝牙是20字节一包这样发送的

我下了源码放到APP里，加了时间打印，看了间隔时间应该满足啊

是observer为空了，所以没有回调 D/EasyBLE: 2022-05-19 15:08:20:047 characteristic change!

之前observer为空是因为连接时没加，但是加了以后还是一样没回调第二条

我尝试在连接到时候设置了setBluetoothGattCallback，这样可以收到数据，但变成2个进程了，会造成我拼包那里出问题

phoebewow commented 2 years ago

加了线程锁之后就没问题了，但是observer没回调的应该还是要看看怎么解决吧？

我验证了下，并没有出现你反馈的问题
