蓝牙技术正在蓬勃发展,预计到2021年将有超过480亿的安装基数(per ABI Internet of Everything Market Tracker)。 那么蓝牙是如何工作的呢?BLE(蓝牙低功耗) 在2.4GHz的ISM频段中有40个物理信道,每个信道之间相隔2MHz。蓝牙定义了两种传输类型:数据传输和广播传输。因此,这40个频道中有3个专门用于广播,37个专门用于数...

Yes it's esp32_ble_tracker causing this. For some reason it likes to break WiFiClient. I looked into it some time ago and wasn't able to create a patch. Error reading data! Main error, the WiFi Client drops the connection Too many BLE events to process. Some devices may not show ...

蓝牙就在我们身边:电子信标引导消防员穿过建筑物; 可穿戴医疗设备将患者的生物数据发送给医生的平板电脑; 40万平方英尺仓库的设备监控等。蓝牙技术正在蓬勃发展,预计到2021年将有超过480亿的安装基数(per ABI Internet of Everything Market Tracker)。 那么蓝牙是如何工作的呢?BLE(蓝牙低功耗) 在2.4GHz的ISM频段中...
Anyway, somewhere in between Android 5.0 and Android 6.0, there was a bug that could corrupt the state of Bluetooth during BLE scans so severely that the users had to hard-reset the device. All the details of that particular bug are outlined in Google’sissue tracker, the critical thing to...
我司准备用esp32-c3的芯片做主控来开发一tracker类的产品,其中功耗是关键参数,应用场景是蓝牙与手机保持连接、wifi作辅助定位。目前我们买了两块开发板 2024-06-12 08:30:53 乐鑫ESP32-P4芯片应用,WT99P4C6-S1开发板应用方案 在物联网和智能硬件的浪潮中,性能卓越、成本效益高的解决方案一直是开发者们追求...
