我寫信給您是因為我需要幫助轉換來自 BLE 設備的回復，我想將其轉換為可理解的資料，但我沒有做到。我正在使用 React 原生 BLE 管理器庫，藍牙設備的檔案是這樣的。
"peripheral": "D6:AD:15:67:4A:A5", "service": "XXXXX-XXXXX-XXXXXX", "value": [85, 0, 255, 0, 0, 13, 0, 96, 93, 0, 0, 0, 0, 0, 49, 0, 0, 0, 1, 0]
uj5u.com熱心網友回復：
從外圍設備回傳的值似乎映射到檔案，如下所示：
85 = 0x55 = ACK Header
0 = 0x00 = ACKCMD
255 = 0xFF = ~ACKCMD_OK
0, 0 = 0x0000 = ACK_PKT_NR
13, 0 = 0x0d = ACK_BUF_SIZE
96 = 0x60 = SpO2
93, 0 = 0x5d00 = Pulse Rate
0, 0, 0, 0 = 0x00000000 = Step Count
49 = 0x31 = Battery
0 = 0x00 = Charging Status
0 = 0x00 = 3-axis
0 = 0x00 = PI
1 = 0x01 = Current state
0 = 0x00 = Reserved
要獲得這些值，代碼將類似于：
const bytes = new Uint8Array([85, 0, 255, 0, 0, 13, 0, 96, 93, 0, 0, 0, 0, 0, 49, 0, 0, 0, 1, 0]);
const pulse = new DataView(bytes.buffer).getUint16(8, true)
const battery = new Uint8Array(bytes.buffer)[14];
console.log('Pulse Rate:' pulse);
console.log('Battery Leve:' battery);轉載請註明出處，本文鏈接：https://www.uj5u.com/qukuanlian/392308.html
