1. Kana iyo baud rate yaiswa, iyo chip ichaibata nemusoro. Nguva inotevera paunoibatidza, chiyero chebaud ndicho chaunoseta.
2. Mushure mekuisa chiyero chebaud, ndapota mirira kwesekondi 1, wozotumira reset [AT+CZ], kana kudzima.
3. Kana iwe uchida kudzoreredza iyo yakasarudzika baud mwero, ndapota tumira iwo murairo kuti udzorere zvigadziriso zvefekitori, ipapo chip chinozodzima zvese zvigadziriso.

Module reset uye fekitori reset

Reset command: AT+CZ\r\n
Ndapota mirira imwe sekondi mushure mekuisa reset rairo

Factory reset command: AT+CW\r\n
Ndokumbira umirire masekonzi mashanu mushure mekupinda mufekitori reset command

Seta zita nekero yeBluetooth

AT+BMBLE-Waveshare\r\n	Seta BLE Bluetooth zita ku "BLE-Waveshare"
AT+BN112233445566\r\n	Seta kero yeBLE. Kero inoratidzwa panhare mbozha inoti: 66 55 44 33 22 11
AT+BDSPP-Waveshare\r\n	Seta iyo SPP Bluetooth zita ku "SPP-Waveshare"

1. Mushure mekuisa zita reBluetooth, ndapota gadzirisazve module, uye shandisa nhare mbozha kutsvaga zvakare mushure mekugadzirisa.
2. Hurefu hwepamusoro hwezita reBluetooth 30 bytes
3. Mushure mekugadzirisa zita reBluetooth, kana zita rekushandisa rinoratidzwa parunhare mbozha rikasachinja, chikonzero chikuru chingave chekuti hauna kushandura kero yeBluetooth, zvichiita kuti nharembozha isagadziriswe synchronously. Panguva ino, chaunofanirwa kuita kushandura ruzivo rwekubatanidza parunhare mbozha. Dzima uye tsvaga zvakare, kana kutsvaga nemumwe mudziyo.

Bvunza zita nekero yeBluetooth

AT+TM\r\n	Dzorera TM+BLE-Waveshare\r\n yezita reBluetooth BLE-Waveshare
AT+TN\r\n	Inodzosa kero yeBluetooth yeTN+12345678AABB\r\n BLE: 0xBB, 0xAA, 0x78, 0x56, 0x34, 0x12
AT+TD\r\n	Dzokera kuTD+SPP-Waveshare\r\n kune Bluetooth zita SPP-Waveshare

Iko hakuna kero yeSPP ingave yakaiswa kana kubvunzwa, nekuti kero yeSPP inowanikwa ne +1 pa
yepamusoro bhaiti yekero yeBLE MAC, yeexample:
Kero yeBLE inodzoserwa se: TN+32F441F495F1,
Izvi zvinoreva kuti kero yeBLE ndeiyi: 0xF1 , 0x95 , 0xF4 , 0x 41 , 0xF4 , 0x32
Ipapo kero yeSPP inoti: 0xF2 , 0x95 , 0xF4 , 0x 41 , 0xF4 , 0x32

Chip yakaderera simba kuraira tsananguro

AT+CL00\r\n	Usaise low power mode. Ichashanda pane inotevera simba-kuban. Ngwarira kuti utangezve simba mushure mekugadzirisa
AT+CL01\r\n	Pinda low power mode. Inoshanda pakubatidza magetsi kunotevera. Mushure mekugadzirisa, teerera kune simba zvakare - iyo chip inopinda mune ino mamiriro nekukasira, hapana chikonzero chekuisa
AT+QL\r\n	Yakaderera-simba query command. Iko kukosha kwekudzoka ndeye QL+01\r\n, zvichiratidza kuti ikozvino kushanda mamiriro emagetsi mashoma ekushandisa

1. Mushure mekuseta, iwe unofanirwa kubatidza zvakare kuti uvandudze iyo gadziriso
2. Murairo uyu wakachengetwa mumusoro. Mushure mekunge murairo watumirwa zvinobudirira, chip ichaichengetedza.
3. Mushure mekutanga iyo yakaderera-simba modhi, pane zvakawanda zvirambidzo, izvo zvinowanzovharwa nekutadza.
4. Mushure mekuseta, chip inodzokera kuruzivo rwechishandiso kazhinji kana yabatidzwa. AT mirairo inogona kusetwa mukati me5 masekonzi, uye mushure memasekonzi mashanu, chero mirairo yeAT icharegeredzwa pamberi pekubatanidza kweBluetooth.
5. Musiyano uripo pakati pekushandiswa kwakaderera kwesimba uye kushanda kwakajairika kunonyanya kukonzerwa nemusiyano wenzira yekutepfenyura kweBluetooth kana Bluetooth isina kubatana. Panguva yekushanda kwakajairika, Bluetooth inogara iri munzvimbo yekutepfenyura. Panguva yekushandiswa kwemagetsi kushoma, inotepfenyura masekonzi 0.5 ega ega, kamwe chete masekonzi 0.1, uye imwe nguva inenge iri mukurara. Kana yakabatana neBluetooth, mashandisirwo emagetsi maviri ekushanda modes akafanana (hongu,
   iyo yakaderera mashandisirwo emagetsi ichave yakaderera zvishoma), Kana iyo isinganyanyi kutarisisa mashandisiro emagetsi kana ichange iri munzvimbo yakadzimwa kwenguva yakareba mushure memagetsi-pa, zviri nani kuchengeta module iri mune yakajairika kushanda mamiriro.
6. Tafura inotevera ndiyo iripo pasi penyika yega yega inoshanda, inoyerwa munzvimbo yekuyedza, uye mhedzisiro ndeyekutarisa chete.

	Siriyero nhamba	Current	Tsanangudzo
AT+CL00\r\n   Low power working mode	Boot moment	12mA	Kana iyo chip ichibatidzwa, ma peripherals anofanirwa kutangwa. Ikozvino pakarepo yakakura, uye nguva ino inochengeterwa 300ms, uye inopinda pasi-simba simba.
	Kushanda Status - Haina Kubatanidzwa	1mA, 5mA alternately	Iyo chip iri mune yakajairika kushanda mamiriro, inotepfenyura zvakajairika, uye iri mune nguva nenguva yekurara, kumuka-kutepfenyura, uye kurara. Chinangwa ndechekuchengetedza mashandisirwo emagetsi, kutenderera kuri 500ms. 100ms kutepfenyura kamwe chete, 400ms kurara
	Mamiriro ekushanda - kubatanidza	6mA	Kana kubatana kuchinge kwabudirira, chip hachichaendi kunorara. asi kubasa
AT+CL01\r\n   zvakajairika kushanda mode	Boot moment	25mA	Kana iyo chip ichibatidzwa, ma peripherals anofanirwa kutangwa. Iyo yekukurumidza iripo yakakura, nguva ino inochengeterwa 300ms, uye inopinda mu5mA inoshanda mamiriro.
	Ingave yakabatana kana kwete	6.5mA	Iyo chip inogara ichishanda. Kuchinja kudiki mune zvazvino, kusakosha

Kana iwe uchinzwa kuti mashandisirwo emagetsi ari pamusoro akakwira, unogona kushandisa 3.3V kupa zvakananga simba kune module uye yazvino ichaenderera mberi.

kuderedza

Chip BLE gonesa uye SPP inogonesa

AT+B401\r\n	Gonesa basa reBLE. Chokwadi AT+B400\r\n yakavharwa
AT+B500\r\n	Dzima basa reSPP. Chokwadi AT+B501\r\n yakabatidzwa
AT+T4\r\n	Tarisa uone kana basa reBLE rakabatidzwa. Iyo chip ichadzorera T4+01 kana T4+00
AT+T5\r\n	Tarisa uone kana SPP basa rakabatidzwa. Iyo chip ichadzosa T5+01 kana T5+00

1. Mushure mekunge basa reBLE/SPP radzimwa, rinofanirwa kuitwa simba zvakare kuti basa iri ritange kushanda. Chokwadi zvakangofanana
2. Iwe unongofanirwa kuseta kamwe chete, iyo chip inochengetedza otomatiki paramita, uye haufanirwe kuimisa nguva inotevera.
3. Mushure mokunge BLE / SPP basa radzimwa, nharembozha haigoni kutsvaga zita reBLE.

Tsananguro yemeseji yezvikanganiso yakadzoserwa nechip

ER+1\r\n	Yakagamuchira data frame haina kururama
ER+2\r\n	Murairo wakagamuchirwa haupo, kureva kuti, tambo yakaita seAT + KK yawakatumira haigoni kuva

	akawana
ER+3\r\n	Murairo wakagamuchirwa weAT hauna kugamuchira kutakura kudzoka uye mutsara wekudya, kureva, \r\n
ER+4\r\n	Iyo parameter inotumirwa nemirairo iri kunze kwehuwandu, kana iyo yekuraira fomati haina kururama. Ndokumbira utarise yako AT mirairo
ER+7\r\n	Iyo MCU inotumira data kunhare mbozha, asi nhare mbozha haivhure ziviso. Mune yakabudirira mamiriro eBLE kubatana

Tarisa pane tsananguro yekuzivisa [monitoring]. Mushure meyedzo APP parunhare mbozha yakabatana neBluetooth chip, ziviso inofanira kuvhurwa. Iyo bluetooth chip inogona
tumira data kunhare mbozha. Kana mbozhanhare ichitumira data kuBluetooth chip, inokwana kushandisa chinyorwa chekunyora.

Chip simba-pa callback ruzivo zvigadziriso

AT+CR00\r\n	Dzima mameseji ekumashure kuti ubatidze. Ngwarira kuti utangezve simba mushure mekugadzirisa
AT+CR01\r\n	Vhura meseji yekudzoka ye chip power-on. Inoshanda pakubatidza magetsi kunotevera. Ngwarira kuti utangezve simba mushure mekugadzirisa

Cherechedza: Mushure mokunge basa iri radzimwa, richadzimawo OK kana ER + X yekudzorera ruzivo iyo inoshingaira kudzorerwa mushure mokunge AT yekuraira yaitwa. Inokurudzirwa kuti irambe yakabatidzwa pano.

Transparent transmission tsananguro

1. Mushure mekubatanidza kweBluetooth, moduru inongopinda inoonekera yekufambisa modhi. Kunze kweiyo chaiyo AT yekuraira, iyo yese data ichaendeswa pachena.
2. Huwandu hwehuwandu hwe data hunogona kubatwa munguva imwe chete ndeye 1024 bytes. SPP inokurudzira kuti haifanirwe kudarika 512 bytes panguva.
3. Iyo MTU (yakanyanya kureba yekutaurirana packet) yeApp nharembozha kazhinji inosarudzika kusvika kumakumi maviri mabhayithi e20 data packet; apo data packet inotumirwa ne module inodarika 1 bytes, module ichaparadzanisa pakiti maererano neMTU yakatarwa; iwe unogona Gadzirisa iyo MTU kushandura iyo data yekudyidzana kumhanya (iyo yakakura iyo
   MTU, iyo inokurumidza kukurumidza kusangana kwedata).
