Kodi HID ndi chiyani
Gulu la HID (Human Interface Device) ndi gawo loyamba la USB lothandizidwa ndi Windows. Amadziwika ndi dzina lake kuti zida za HID ndi zida zomwe zimalumikizana mwachindunji ndi anthu, monga kiyibodi, mbewa, ndi zokometsera. Komabe, zida za HID sizikhala ndi mawonekedwe a makina amunthu, bola ngati zikugwirizana ndi mawonekedwe amtundu wa HID, onse ndi zida za HID.
Mu protocol ya HID, pali mabungwe awiri: "host" ndi "chipangizo". Chipangizochi ndi chinthu chomwe chimalumikizana mwachindunji ndi munthu, monga kiyibodi kapena mbewa. Wothandizira amalumikizana ndi chipangizocho ndipo amalandira zolowa kuchokera ku chipangizocho pazochita zomwe munthu amachita. Deta yotulutsa imayenda kuchokera pagulu kupita ku chipangizo kenako kupita kwa munthu. Chitsanzo chodziwika bwino cha wolandila ndi PC koma mafoni ena am'manja ndi ma PDA amathanso kukhala olandila.
FSC-BP102 yopangidwa ndi Feasycom. Imathandizira mbiri zonse za SPP ndi BLE ndipo ili ndi mawonekedwe a USB. Mawonekedwe a USB ali ndi ntchito ziwiri: doko la serial ndi kiyibodi ya HID. Kusintha kwa data kwa Bluetooth kupita ku HID ndi Bluetooth serial port transparent transmission function zitha kuchitika.
Chithunzi cha FSC-BP102
1. Kodi ntchito ya Bluetooth kusamutsa deta ku HID ndi chiyani?
Ogwiritsa ntchito amatha kulumikizana ndi chipangizo cha FSC-BP102 kudzera pa Bluetooth ndikutumiza deta kwa icho ndi mbiri ya SPP kapena BLE. FSC-BP102 idzasintha zomwe zalandilidwa ndikuzitulutsa kwa wogwirizira wolumikizidwa mu mawonekedwe a HID.
2. Kodi ntchito ya Bluetooth siriyo doko transparent kufala?
Ogwiritsa ntchito amatha kulumikizana ndi FSC-BP102 kudzera pa Bluetooth ndikutumiza deta ku FSY-BP102 kudzera pa SPP kapena BLE. FSC-BP102 idzatulutsa zomwe zalandiridwa kwa wolandirayo kudzera pa doko la serial.
Izi zimagwiritsa ntchito BT836 gawo yankho, BT836 gawo ndi spp ndi BLE wapawiri mode Bluetooth 4.2 gawo. Mlingo wotumizira: BLE: 8KB/S, SPP: 80KB/S, mphamvu yotumizira 5.5dBm, yokhala ndi mlongoti wokwera, yogwira ntchito mpaka 10m. Amagwiritsidwa ntchito kwambiri mu mawotchi anzeru, zida zathanzi ndi zamankhwala, POS opanda zingwe, makina oyezera ndi kuyang'anira, masensa amakampani ndi owongolera osindikiza a Bluetooth ndi mapulogalamu ena.
