關於Running Speed and Cadence profile問題請教

Other Parts Discussed in Thread: CC2541

1、贴子标题简要概况求助要点

小弟是ODM廠的RD,目前收到一客戶RFQ是關於BLE的Running Speed and Cadence profile,看了一下SPEC回傳的資料如下:

Mandatory:
Instantaneous Speed (Unit is in m/s with a resolution of 1/256 s)
Instantaneous Cadence (Unit is in 1/minute (or RPM) with a resolutions of 1 1/min)
Optional:
Instantaneous Stride Length (Unit is in meter with a resolution of 1/100 m or centimeter)
Total Distance (Unit is in meter with a resolution of 1/10 m or decimeter)
Sensor Location(feature)
Walking or Running Status(feature)

Sample code看起來是回傳emulation data給手機,沒有去真正讀取周邊裝置運算

想請問Instantaneous Speed、Instantaneous Stride Length和Instantaneous Cadence一般來說是由G-Sensor求得的嗎?

還是需要搭配其他的sensor? TI有建議的solution嗎? (sensor & sample code)

2、清楚描述背景信息

A。目前使用的芯片是CC2541

B。硬件环境:使用CCDebugger進行燒錄.hex檔案

C。软件环境:IAR for 8051 v8.20.2

D。其他:

3、请说明您处于开发设计的哪个阶段? RFQ

4、您对TI产品的了解程度:已使用一年多,已有一產品使用MSP430F5524進入量產,一產品使用MSP430F5510正在EVT,一產品使用CC2541進入PVT。
