思为无线蓝牙模块BLE5101通讯距离测试演示
G-NiceRF思为无线的BLE5101是一款小体积、低功耗、主从角色并存的蓝牙模块,那么这款产品的通讯距离有多远呢?接下来由思为无线小编给大家演示实际测试流程。
测试工具:
2个蓝牙模块BLE5101, 烧录测试程序进行自动收发,进行双向通信。
3.3V的电池2个
(蓝牙模块BLE5101裸板接线背面图)
(蓝牙模块BLE5101裸板接线正面图)
蓝牙默认连接参数设置:
mininum connection interval: 7.5ms
maxnum connection interval: 7.5ms
number of slave latency: 0
supervision timeout of the link: 5s
测试天气:晴天 31℃
接下来进行测试,测试地点选取在兴华一路的大道上,将蓝牙模块BLE5101①接通电源。
(板上焊接出来的绿灯是测试用的接收指示灯,接收到对端发送过来的数据时会闪烁一次)
①测试距离150m:2个蓝牙模块BLE5101相距150米,接通电源。观察BLE5101①与BLE5101②的连接指示灯(图中的蓝灯)均亮起,说明两个模块已成功建立蓝牙连接并能收发数据。
(150m测试:蓝牙模块BLE5101通讯状态)
从上图可以看出:两个蓝牙模块BLE5101的连接指示灯都亮了,表示两个蓝牙模块已连接并能收发数据,通讯距离150m测试成功。
②测试距离200m:观察BLE5101①与BLE5101②的连接指示灯(图中的蓝灯)是否仍然保持亮起的状态。
(200m测试:蓝牙模块BLE5101通讯状态)
从上图可以看出:BLE5101①与BLE5101②的的连接指示灯熄灭了,表示两个蓝牙模块由于距离过远,连接超时而断开连接,通讯距离200m测试失败。
以上就是蓝牙模块BLE5101通讯距离的测试过程分享。如果您对G-NiceRF思为无线的蓝牙模块BLE5101感兴趣,欢迎咨询世强平台工作人员获取最新产品信息。
