1. Uma isilinganiso se-baud sisethiwe, i-chip izoyibamba ngekhanda. Ngokuzayo uma uyivula, izinga le-baud kuzoba yilelo olisethayo.
2. Ngemva kokusetha izinga le-baud, sicela ulinde isekhondi elingu-1, bese uthumela ukusetha kabusha [AT+CZ], noma ucime.
3. Uma ufuna ukubuyisela izinga le-baud elizenzakalelayo, sicela uthumele umyalo wokubuyisela izilungiselelo zasefekthri, bese i-chip izosula ngokuzenzakalelayo konke ukulungiselelwa.

Ukusetha kabusha imojuli nokusetha kabusha njengasekuqaleni

Setha kabusha umyalo: AT+CZ\r\n
Sicela ulinde isekhondi elilodwa ngemva kokufaka umyalo wokusetha kabusha

Umyalo wokusetha kabusha kwasefekthri: AT+CW\r\n
Sicela ulinde imizuzwana emihlanu ngemva kokufaka umyalo wokusetha kabusha njengasekuqaleni

Setha igama nekheli le-Bluetooth

AT+BMBLE-Waveshare\r\n	Setha igama le-Bluetooth le-BLE libe yi-“BLE-Waveshare”
AT+BN112233445566\r\n	Setha ikheli le-BLE. Ikheli elivezwe kumakhalekhukhwini lithi: 66 55 44 33 22 11
AT+BDSPP-Waveshare\r\n	Setha igama le-Bluetooth le-SPP ku-“SPP-Waveshare”

1. Ngemva kokusetha igama le-Bluetooth, sicela usethe kabusha imojuli, bese usebenzisa iselula ukuze useshe futhi ngemva kokusetha kabusha.
2. Ubude obukhulu begama le-Bluetooth ngamabhayithi angama-30
3. Ngemva kokulungisa igama le-Bluetooth, uma igama ledivayisi elivezwa kumakhalekhukhwini lingashintshi, isizathu esiyinhloko kungaba ukuthi awukalishintshi ikheli le-Bluetooth, okuholela ekutheni iselula ingabuyekezwa ngokuhambisanayo. Ngalesi sikhathi, okudingeka ukwenze ukushintsha imininingwane yokumatanisa kumakhalekhukhwini. Susa bese usesha futhi, noma sesha ngenye idivayisi.

Buza igama nekheli le-Bluetooth

AT+TM\r\n	Buyisa i-TM+BLE-Waveshare\r\n ukuze uthole igama le-Bluetooth BLE-Waveshare
AT+TN\r\n	Ibuyisela ikheli le-Bluetooth le-TN+12345678AABB\r\n BLE: 0xBB, 0xAA, 0x78, 0x56, 0x34, 0x12
AT+TD\r\n	Buyela ku-TD+SPP-Waveshare\r\n ukuze uthole igama le-Bluetooth elithi SPP-Waveshare

Alikho ikheli le-SPP noma lisethiwe noma liyabuzwa, ngoba ikheli le-SPP litholwa ngo +1 ku
Ibhayithi ephezulu kakhulu yekheli le-BLE MAC, ngokwesiboneloample:
Ikheli le-BLE libuyiselwa njenge: TN+32F441F495F1,
Lokhu kusho ukuthi ikheli le-BLE lithi: 0xF1 , 0x95 , 0xF4 , 0x 41 , 0xF4 , 0x32
Bese ikheli le-SPP lithi: 0xF2 , 0x95 , 0xF4 , 0x 41 , 0xF4 , 0x32

Incazelo yemiyalelo ye-Chip yamandla aphansi

AT+CL00\r\n	Ungafaki imodi yamandla aphansi. Izosebenza ekukhanyiseni okulandelayo. Qaphela ukuqalisa kabusha amandla ngemva kokusetha
AT+CL01\r\n	Faka imodi yamandla aphansi. Isebenza ekukhanyiseni okulandelayo. Ngemva kokusetha, naka amandla futhi - i-chip ingena kulesi simo ngokuzenzakalelayo, asikho isidingo sokusetha
AT+QL\r\n	Umyalo wombuzo wamandla aphansi. Inani lokubuyisela lingu-QL+01\r\n, okubonisa ukuthi isimo samanje sokusebenza siyimodi yokusetshenziswa kwamandla okuphansi

1. Ngemva kokusetha, udinga ukuvula futhi ukuze ubuyekeze ukucushwa
2. Lo myalo ubanjwe ngekhanda. Ngemuva kokuthi umyalo uthunyelwe ngempumelelo, i-chip izowugcina.
3. Ngemva kokuqala imodi yamandla aphansi, kunemikhawulo eminingi, ngokuvamile evalwa ngokuzenzakalelayo.
4. Ngemva kokusetha, i-chip izobuyela olwazini lwedivayisi ngokujwayelekile uma ivuliwe. Imiyalo ye-AT ingasethwa phakathi kwamasekhondi angu-5, futhi ngemva kwamasekhondi angu-5, noma yimiphi imiyalo ye-AT izozitshwa ngaphambi kokuxhumeka kwe-Bluetooth.
5. Umehluko phakathi kokusetshenziswa kwamandla okuphansi nokusebenza okuvamile ubangelwa ikakhulukazi umehluko endleleni yokusakaza kwe-Bluetooth uma i-Bluetooth ingaxhunyiwe. Ngesikhathi sokusebenza okuvamile, i-Bluetooth ihlezi isesimweni sokusakaza. Ngesikhathi sokusetshenziswa kwamandla okuphansi, isakaza njalo ngemizuzwana engu-0.5, kanye njalo ngemizuzwana engu-0.1, kanti sonke isikhathi sisesimweni sokulala. Uma uxhumeke ku-Bluetooth, ukusetshenziswa kwamandla kwezindlela ezimbili zokusebenza kuyefana (Yebo,
   ukusetshenziswa kwamandla okuphansi kuzoba ngaphansi kancane),Uma ingazweli ikakhulukazi ekusetshenzisweni kwamandla noma izoba sesimweni sokunqanyulwa isikhathi eside ngemva kokukhanyisa, kungcono ukugcina imojula isesimweni esivamile sokusebenza.
6. Ithebula elilandelayo elamanje ngaphansi kwesimo ngasinye sokusebenza, esilinganiswa endaweni yokuhlola, futhi imiphumela ingeyereferensi kuphela.

	Inombolo yomkhiqizo	Okwamanje	Incazelo
AT+CL00\r\n   Imodi yokusebenza yamandla aphansi	Isikhathi sokuqalisa	12mA	Uma i-chip ivuliwe, ama-peripherals adinga ukuqaliswa. I-current esheshayo inkulu kakhulu, futhi lesi sikhathi sigcinwa ku-300ms, futhi singena esimweni samandla aphansi.
	Isimo Sokusebenza - Akuxhunyiwe	1mA, 5mA ngokushintshana	I-chip isesimweni esivamile sokusebenza, isakaza ngokuvamile, futhi isesimweni sokulala ezikhathini ezithile, ukusakazwa kokuvuka, nokulala. Inhloso ukusindisa ukusetshenziswa kwamandla, umjikelezo ungama-500ms. I-100ms isakaza kanye, 400ms ukulala
	Isimo sokusebenza - ukuxhuma	6mA	Uma ukuxhumeka kuphumelele, i-chip ngeke isakwazi ukulala. kodwa emsebenzini
AT+CL01\r\n   imodi yokusebenza evamile	Isikhathi sokuqalisa	25mA	Uma i-chip ivuliwe, ama-peripherals adinga ukuqaliswa. I-current esheshayo inkulu uma kuqhathaniswa, lesi sikhathi igcinwa i-300ms, futhi ingena esimweni sokusebenza esingu-5mA.
	Ukuthi kuxhunyiwe noma cha	6.5mA	I-chip ihlala isebenza. Ukushintshashintsha okuncane kwamanje, akunakwa

Uma uzwa sengathi ukusetshenziswa kwamandla okungenhla kuphezulu uma kuqhathaniswa, ungasebenzisa i-3.3V ukuze unikeze amandla ngqo kumojula futhi owamanje uzoqhubekela phambili.

nciphisa

I-Chip BLE inika amandla futhi i-SPP inika amandla

AT+B401\r\n	Nika amandla umsebenzi we-BLE. Impela i-AT+B400\r\n ivaliwe
AT+B500\r\n	Khubaza umsebenzi we-SPP. Impela i-AT+B501\r\n ivuliwe
AT+T4\r\n	Hlola ukuthi umsebenzi we-BLE uvuliwe yini. I-chip izobuyisela i-T4+01 noma i-T4+00
AT+T5\r\n	Hlola ukuthi umsebenzi we-SPP uvuliwe yini. I-chip izobuyisela i-T5+01 noma i-T5+00

1. Ngemuva kokuthi umsebenzi we-BLE/SPP uvaliwe, kufanele uvulelwe amandla futhi ukuze lo msebenzi uqale ukusebenza. Yebo kuyafana
2. Udinga ukuyisetha kanye kuphela, i-chip igcina ngokuzenzakalelayo amapharamitha, futhi awudingi ukuyisetha ngokuzayo.
3. Ngemuva kokuthi umsebenzi we-BLE/SPP ucishiwe, umakhalekhukhwini awukwazi ukucinga igama le-BLE.

Incazelo yomlayezo wephutha obuyiswe yi-chip

ER+1\r\n	Uhlaka lwedatha olwamukelwe alulungile
ER+2\r\n	Umyalo owamukelwe awukho, okungukuthi, iyunithi yezinhlamvu efana ne-AT+KK oyithumele ayinakuba

	kutholiwe
ER+3\r\n	Umyalo we-AT owamukelwe awutholanga ukubuya kwenqola kanye nokuphakelayo komugqa, okungukuthi, \r\n
ER+4\r\n	Ipharamitha ethunyelwe umyalo ayikho ebangeni, noma ifomethi yomyalo ayilungile. Sicela uhlole imiyalo yakho ye-AT
ER+7\r\n	I-MCU ithumela idatha kumakhalekhukhwini, kodwa iselula ayivuli yazisa. Esimeni esiyimpumelelo soxhumano lwe-BLE

Gxila encazelweni yokwazisa [ukuqapha]. Ngemuva kokuthi i-APP yokuhlola kumakhalekhukhwini ixhunywe ku-chip ye-Bluetooth, isaziso kufanele sivulwe. I-bluetooth chip can
thumela idatha kumakhalekhukhwini. Uma umakhalekhukhwini uthumela idatha ku-chip ye-Bluetooth, kwanele ukusebenzisa isici sokubhala.

Izilungiselelo zolwazi lokuphinda ushayele amandla e-Chip

AT+CR00\r\n	Vala imilayezo ye-postback ukuze uvule. Qaphela ukuqalisa kabusha amandla ngemva kokusetha
AT+CR01\r\n	Nika amandla umlayezo obuyayo wokuvula amandla e-chip. Isebenza ekukhanyiseni okulandelayo. Qaphela ukuqalisa kabusha amandla ngemva kokusetha

Qaphela: Ngemva kokuba lo msebenzi uvaliwe, uzophinda uvale OK noma ER+X ulwazi lokubuyisela olubuyiswa ngokuqhubekayo ngemva kokukhishwa komyalo we-AT. Kunconywa ukuthi uyigcine ivuliwe lapha.

Incazelo yokudlulisela esobala

1. Ngemva kokuxhumeka kwe-Bluetooth, imojuli ingena ngokuzenzakalelayo kumodi yokudlulisela esobala. Ngaphandle komyalo olungile ngokuphelele we-AT, yonke idatha izodluliswa ngokusobala.
2. Inani eliphakeme ledatha elingaphathwa ngesikhathi esisodwa amabhayithi angu-1024. I-SPP incoma ukuthi akumele idlule amabhayithi angu-512 ngesikhathi.
3. I-MTU (ubude bephakethe lokuxhumana eliphakeme kakhulu) ye-APP yeselula ngokuvamile ishintshashintsha ibe ngamabhayithi angu-20 ngephakethe ledatha elingu-1; lapho iphakethe ledatha elithunyelwe yi-module lidlula ama-byte angu-20, i-module izohlukanisa ngokuzenzakalelayo iphakethe ngokusho kwesethi ye-MTU; Ungashintsha i-MTU ukuze uguqule isivinini sokusebenzisana kwedatha (okukhudlwana i-
   I-MTU, isivinini sokusebenzisana kwedatha siyashesha).
