[求助问答] 手机无法用BlunoBasicDemo 搜索到RoMeo BLE | 
| 
求各位大神!如何用手机连接上RoMeo BLE v1.0或Beetle BLE板子? 我按照资料库里的提示,板子下载了代码: void setup() { Serial.begin(115200); //initial the Serial } void loop(){ if(Serial.available()) { Serial.write(Serial.read()); //send what has been received Serial.println(); //print line feed character } } 接着把固件升级到了Bluno_V1.97。 然后手机安装了BlunoBasicDemo 软件。 但是APP就是没有SCAN到板子,点击Scan什么都没有。 请教各位大神,有哪位大神能帮忙指点一下。或者其他办法能让手机通过蓝牙连接到板子。(我的手机是华为p20)  |
