Android蓝牙发指令闪退 #73
Comments
换了台PC配对后可以连接 但是无法发送和接收指令,同样设置在Android手机上可以读写 |
已经找到原因,BLE模组低功耗模式下未经过鉴权30S自动断开,断开后点击操作会闪退,BLEtoUart模组波特率只有115200传输速率没发的快,所以包全丢了,在设置中降速后解决,Windows无法通讯未解决 |
还有一种可能是设备底层有MTU限制,一次最多只能发送指定数量的字节。这种情况目前也是要配置降速才能解决。 |
感谢回复,开始是下的MinGW版本需要匹配才能在中心设备中找到BLE设备,连接后无法通讯(感觉像是假连接,因为秒连) |
蓝牙发送指令app会闪退,传输文件的话只能传96位。后面就没了;
尝试用Windows端WIN11的系统不知道为啥检测不到这个蓝牙号,只能检测到手机、耳机等设备。使用系统自带的蓝牙可以检测到。
好不容能找到一个支持发送文件的蓝牙工具,谢谢大佬
