Ntev ntau lub suab module HFP xeem daim ntawv qhia

Long range audio module Test Ib puag ncig:

Hnub ci; Tsis muaj teeb meem nyob ib puag ncig; Txoj kev ncaj; Cov khoom yog 1.5m saum av.

Kev npaj xeem: 909 Master +909 qhev

1. Npaj ob BT909 modules, firmware version: VER=FSC-BT909, V3.2.6, 20181105.
2. solder ob BT909s rau lub rooj tsavxwm tus ntxhais thiab npaj ob pawg ntawm FSC-TL001 kev loj hlob boards nrog Codec.
3. Nruab ob lub BT909s ntawm FSC-TL001 pawg thawj coj saib xyuas kev txhim kho thiab muab lub zog rau lawv cais nrog ob lub khoos phis tawj.
4. Xa AT hais kom hloov hom ntawm ob BT909 modules:

        Master hom hais kom ua: AT + PROFILE = 19

        Cov lus txib hom qhev: AT + PROFILE = 1707

Cov kauj ruam txuas: 

1. Siv cov cuab yeej serial chaw nres nkoj los nug MAC chaw nyob code ntawm tus qhev module.
     Hais kom ua: AT + ADDR

2. Master module txuas mus rau qhev module ntawm cov cuab yeej serial chaw nres nkoj.  
    XXXXXXXXXXXX sawv cev rau kaum ob-ntsis qhev MAC chaw nyob.
    AT cov lus txib ntawm kev txuas mus rau qhev module: AT+HFPCONN=XXXXXXXXXXXX

3. Tom qab kev sib txuas ua tiav, tus tswv module xa cov lus txib mus rau qhev module ntawm serial chaw nres nkoj cuab yeej.
    Command: AT+HFPAUDIO=1

Cov kauj ruam xeem:

1. Txuas lub mloog pob ntseg lossis hais lus rau hauv SPK2 interface ntawm ob lub rooj tsav xwm loj hlob FSC-TL001.
2. Lub suab tuaj yeem hnov ​​​​los ntawm lub mloog pob ntseg lossis hais lus ntawm tus tswv FSC-TL001 kev txhim kho pawg thawj coj saib thaum hais lus ntawm MIC ntawm qhev FSC-TL001 pawg thawj coj saib xyuas.
3. Lub suab tuaj yeem hnov ​​​​los ntawm lub mloog pob ntseg lossis hais lus ntawm tus qhev FSC-TL001 pawg thawj coj saib xyuas kev txhim kho thaum hais lus ntawm MIC ntawm tus tswv FSC-TL001 pawg thawj coj saib xyuas.
4. Kho ib qho ntawm ob lub cuab yeej, txav mus rau lwm qhov, hais lus, xyuas kom lub suab zoo meej, tsis muaj suab nrov, qhov deb tshaj plaws yam tsis muaj kev hloov pauv

Cov txiaj ntsig kuaj:

Qhov kev ncua deb tshaj plaws yog 90m, yog tias tawm ntawm qhov ntau, lub suab yuav muaj suab nrov, tshee tshee, cuam tshuam thiab lwm yam teeb meem.
Yog tias koj txaus siab rau qhov module no, tiv tauj peb kom paub ntau ntxiv. Ua tsaug!
