Thaum nws los txog rau Bluetooth cov khoom tsim, Baud Rate ntawm Bluetooth module yog qhov tseem ceeb.
Tus nqi baud yog dab tsi?
Tus nqi baud yog tus nqi ntawm cov ntaub ntawv xa mus rau hauv kev sib txuas lus. Hauv cov ntsiab lus ntawm qhov chaw nres nkoj serial, "11200 baud" txhais tau hais tias qhov chaw nres nkoj serial muaj peev xwm hloov tau qhov siab tshaj plaws ntawm 11200 khoom ib ob.

Yuav ua li cas hloov tus nqi baud ntawm Bluetooth module nrog AT cov lus txib?
Yooj yim heev!
AT + BAUD = {'Tus baud tus nqi koj xav tau'}
Piv txwv li, yog tias koj xav hloov tus nqi baud ntawm ib qho module rau 9600, koj tuaj yeem siv yooj yim,
AT + BAUD = 9600
Saib daim duab siv hauv qab no, peb siv FSC-BT836 los ntawm Feasycom ua piv txwv. Lub neej ntawd baud tus nqi ntawm no high-ceev Bluetooth module yog 115200. Thaum xa AT + BAUD = 9600 rau cov module no nyob rau hauv AT command hom, nws baud tus nqi tau hloov mus rau 9600 tam sim ntawd.
