心率带调试数据整理
1.低功耗蓝牙4.0 连接
返回的service数据如下
{"name":"Polar H7 D445C114","id":"00:22:D0:D4:45:C1","advertising":{},"rssi":-46,"services":["1800","1801","180d","180a","180f","6217ff4b-fb31-1140-ad5a-a45545d7ecf3"],"characteristics":[{"service":"1800","characteristic":"2a00","properties":["Read","WriteWithoutResponse","Write"]},{"service":"1800","characteristic":"2a01","properties":["Read"]},{"service":"1800","characteristic":"2a02","properties":["Read","Write"]},{"service":"1800","characteristic":"2a03","properties":["Write"]},{"service":"1800","characteristic":"2a04","properties":["Read"]},{"service":"1801","characteristic":"2a05","properties":["Indicate"],"descriptors":[{"uuid":"2902"}]},{"service":"180d","characteristic":"2a37","properties":["Notify"],"descriptors":[{"uuid":"2902"}]},{"service":"180d","characteristic":"2a38","properties":["Read"]},{"service":"180a","characteristic":"2a23","properties":["Read"]},{"service":"180a","characteristic":"2a24","properties":["Read"]},{"service":"180a","characteristic":"2a25","properties":["Read"]},{"service":"180a","characteristic":"2a26","properties":["Read"]},{"service":"180a","characteristic":"2a27","properties":["Read"]},{"service":"180a","characteristic":"2a28","properties":["Read"]},{"service":"180a","characteristic":"2a29","properties":["Read"]},{"service":"180f","characteristic":"2a19","properties":["Read"]},{"service":"6217ff4b-fb31-1140-ad5a-a45545d7ecf3","characteristic":"6217ff4c-c8ec-b1fb-1380-3ad986708e2d","properties":["Read"]},{"service":"6217ff4b-fb31-1140-ad5a-a45545d7ecf3","characteristic":"6217ff4d-91bb-91d0-7e2a-7cd3bda8a1f3","properties":["Write","Indicate"],"descriptors":[{"uuid":"2902"}]}]}
连接这个服务{"service":"180d","characteristic":"2a37","properties":["Notify"],"descriptors":[{"uuid":"2902"}]},
收取到的数据用uint8Array()初始化，结果如下：
startNotification : 22,84,246,2",startNotification : 22,83,38,3",startNotification : 22,81,27,3,85,3",startNotification : 22,80,104,3",startNotification : 22,79,71,3",startNotification : 22,79,251,2",
每组的第二个数值即是心率。
