Functional Description
PmodBT2 siv tus qauv 12-pin chaw nres nkoj thiab sib txuas lus ntawm UART. Muaj qhov thib ob SPI header ntawm lub rooj tsavxwm rau kev hloov kho RN-42 firmware yog tias xav tau.
1.1 Jumper Chaw
PmodBT2 muaj ntau hom muaj rau cov neeg siv ntawm jumper nqis. JP1 txog JP4 muab ntau hom kev ua haujlwm raws li qhia hauv Table 1 hauv qab no. Txhua jumper yog nquag thaum luv. JP1 rov qab kho lub cuab yeej los ua qhov teeb meem pib tom qab peb qhov kev hloov pauv ntawm qhov chaw jumper (luv-rau-qhib lossis qhib-rau-luv). Tom qab qhov kev hloov pauv thib peb, lub cuab yeej rov qab mus rau qhov tseem ceeb tshwj tsis yog lub npe Bluetooth. Lwm peb jumpers, JP2-JP4, tsuas yog sample hauv thawj 500 ms ntawm kev ua haujlwm kom tso cai rau cov pins uas lawv khi rau ntawm RN-42 module los ua haujlwm rau lwm lub hom phiaj tom qab hauv kev ua haujlwm modules. JP2 enables pairing nrog ib tug tshwj xeeb ntaus ntawv chav kawm ntawv txhais los ntawm tus neeg siv nyob rau hauv software. Qhov no yuav siv tau kom PmodBT2 ua haujlwm hloov pauv rau RS232 cable. JP3 ua rau nws pib txuas mus rau qhov chaw nyob khaws tseg los ntawm tus neeg siv. Thaum kawg, JP4 xaiv seb puas yuav khiav lag luam ntawm qhov khaws cia baud tus nqi (115.2kbps default) lossis baud tus nqi ntawm 9600 tsis hais qhov software xaiv tus nqi thaum luv. Yog xav paub ntxiv txog kev teeb tsa jumper thiab kev ua haujlwm, saib RN-42 cov neeg siv phau ntawv.
| Jumper | Kev piav qhia |
| JP1 (PIO4) | Factory Default |
| JP2 (PIO3) | Auto Discovery / Pairing |
| JP3 (PIO6) | Pib Txuas |
| JP4 (PIO7) | Baud tus nqi (9600) |
Table 1. Teem jumper piav qhia.
1.2 UART interface
Los ntawm lub neej ntawd, UART interface siv tus nqi baud ntawm 115.2 kbps, 8 cov ntaub ntawv khoom, tsis muaj qhov sib luag, thiab ib qho nres me ntsis. Qhov pib baud tus nqi yuav raug kho rau cov nqi teev ua ntej lossis teeb tsa rau tus neeg siv tshwj xeeb customized baud tus nqi.
Predefined baud tus nqi sib txawv ntawm 1200 txog 921k.
Tus pin rov pib dua (RST) ntawm J1 yog qis qis. Yog tias tus pin RST toggled, lub cuab yeej yuav raug rov pib dua. Qhov kev rov ua haujlwm nyuaj no ua tau zoo ib yam li lub zog caij tsheb kauj vab ntawm lub cuab yeej. Qhov thib ob interface dua li tus qauv UART cov cim qhia yog STATUS tus pin kuj ntawm J1Tus STATUS tus pin ncaj qha qhia txog kev sib txuas ntawm lub cuab yeej. STATUS yog tsav siab los ntawm lub cuab yeej thaum txuas thiab tsav qis dua lwm yam.
Yog xav paub ntxiv ntawm cov cuab yeej UART interface thiab RST thiab STATUS pins xa mus rau RN-42 cov neeg siv phau ntawv ntawm Roving Networks webqhov chaw.
1.3 Command Mode
Txhawm rau nkag mus rau hom kev hais kom ua, PmodBT2 yuav tsum tau txais "$$$" uas nws yuav teb "CMD". Thaum nyob rau hauv kev hais kom ua hom, lub module yuav teb rau ib tug loj tus naj npawb ntawm cov lus txib uas tso cai rau tus neeg siv los customizing lub module rau tej kev siv. Txhawm rau tawm ntawm hom kev hais kom ua, xa "— ” (peb lub cim cim hauv kab thiab qhov twg stands rau lub carriage return character) uas lub cuab yeej yuav teb “END”. Kev teeb tsa chaw taws teeb, lossis kev teeb tsa dhau ntawm kev sib txuas Bluetooth, tuaj yeem ua tau los ntawm hom kev hais kom ua tab sis muaj ntau yam kev txwv. Lub sijhawm teeb tsa, uas ua rau 60 sec, txhais lub sijhawm lub qhov rai uas PmodBT2 yuav raug teeb tsa nyob deb. Nyob rau sab nraud ntawm lub sijhawm no, PmodBT2 yuav tsis teb rau cov lus txib tej thaj chaw deb. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias ib qho ntawm "teeb" cov lus txib muaj rau PmodBT2 yuav tsum tau ua raws li lub voj voog hluav taws xob kom siv tau rau txhua qhov tsim.

Ntau hom kev ua haujlwm tau nkag los ntawm kev siv "SM,<5,4,3,2,1,0>" hais kom ua thaum nyob hauv hom lus txib. PmodBT2 tuaj yeem muab tso rau hauv ib qho ntawm rau hom kev ua haujlwm muaj. Cov qauv hauv kev txiav txim, 0 txog 5, yog: qhev, tus tswv, ua tus tswv, nws pib txuas, pib txuas DTR, thiab nws pib-txuas txhua. Yog xav paub ntxiv txog ntau hom kev ua haujlwm, saib RN-42 tus neeg siv phau ntawv. Rau daim ntawv teev tag nrho ntawm cov lus txib, yuav ua li cas rau cov neeg siv emote configuration, thiab cov ncauj lus kom ntxaws ntxiv ntawm ntau hom kev ua haujlwm, saib RN-42 cov ntaub ntawv.
