Peb lub neej ntawd firmware yog hom qhev, koj tuaj yeem saib cov xwm txheej los ntawm kev xa cov lus txib AT + PROFILE.
AT + I2SCFG = 1 I2S yuav raug teeb tsa ua hom tswv
Yog tias txuas nrog HFP, qhov ntsuas yuav yog 8K, 16 ntsis
Yog tias txuas nrog A2DP, qhov ntsuas yuav yog 48K 16 ntsis lossis 44.1K 16 ntsis. Hauv peb cov version tom ntej, nws yuav kho rau 48K 16 ntsis.
AT + I2SCFG = 3 I2S yuav raug teeb tsa ua qhev hom.
Cov kauj ruam ntxaws:
Yog tias koj xav tau txuas rau HFP
- AT + PROFILE = 83
- AT+SCAN=1 piv txwv li koj qhov chaw nyob Bluetooth yog DC0D3000142D
- AT + HFPCONN = DC0D3000142D
- Yog tias koj pom cov lus qhia +HFPSTAT=3, nws txhais tau tias txuas tau zoo.
- AT + HFPAUDIO = 1
Ces lub suab txuas yuav raug tsim.
Kev soj ntsuam logic kom ntes I2S teeb liab, koj tuaj yeem pom 8K 16 ntsis waveform raws li nram no:

Xa AT + I2SCFG = 3, AT + REBOOT hais kom ua, thiab rov ua cov kauj ruam dhau los. Parameters yuav yog
48K, 16 ntsis, 44.1K 16 ntsis, nyob ntawm cov khoom siv qhev.
Txais tos kom sab laj peb cov lus nug ntxiv.
