Fa'amatalaga Taua

1. Fa'alogo lelei i le uaea e pei ona fa'aalia i le ata ma aua le fa'afeso'ota'i sese.
2. O lenei pepa o lo'o fa'atusalia na'o le fa'alauiloaina o oloa ma ta'iala ile taimi ole fa'ata'ita'iga. So'o se suiga e faia i le lumana'i e aunoa ma se fa'aaliga.

• FA'AVAE: Faʻamau Faʻamau Oomi le faʻamau Boot ma taofi (aua le tatalaina le Boot button i le taimi nei) ma ulufale i le mode "download firmware", ma sii mai le firmware e ala i le laina telefoni.
• USB: E mafai ona faʻaaogaina e avea o se eletise i le laupapa matagaluega, poʻo se fesoʻotaʻiga fesoʻotaʻiga fesoʻotaʻi le PC i le ESP32-WROOM-32 module
• Fa'atonuga mo le fa'aoga (fa'aaoga AT firmware e fai ma example):
• O le laupapa atina'e e feso'ota'i i le komepiuta e ala i le Type-C data cable (o lo'o ola le moli fa'ailo pe a uma le fa'aola)
• Tatala la'u komepiuta-Management-Masini Pule i view E masani ona iloa le uafu COM (E le'o fa'apipi'i le fa'ailoga fa'ailoga o lo'o fa'aalia i lalo.

Fua AT polokalame firmware
Tatala le meafaigaluega mu "flash_download_tool" e maua ai le fesoʻotaʻiga polokalame e pei ona taua i lalo https://www.espressif.com/zh-hans/support/download/other-tools

1. Filifili "ESP32" Default "Atiae" e pei ona taua i lalo, kiliki OK
2. U'u le mea ua mu "Ai-Thinker_ESP32_DIO_32Mbit_V2.0_20170324.bin" file
3. A maeʻa ona faʻatulagaina faʻamau, aʻo leʻi kiliki e amata mu, e tatau ona e oomi le
4. A maeʻa le mu, toe tatala le USB ma tatala le fesoʻotaʻiga telefoni fesoasoani e sendAT (toe toe lafo se laina fou, o le baud rate o le 115200). Afai e manuia le poloaiga, o le a toe foi mai OK. E mafai ona e faʻatinoina le faʻaogaina o le WiFi e ala i le mulimuli i le AT command.
   1. Seti le module WiFi mode i le laina
      AT+CWMODE=1 OK
   2. Fa'afeso'ota'i i le WiFi hotspots
      AT+CWJAP=”Igoa WiFi”,”Utulautusi” Ua lelei

WiFi masani download

1. Tatala le 1.8.5 version o Arduino IDE, saili le file →Preferences, ona kopi lea ma faapipii le sootaga o loʻo i lalo i mea e fiafia i ai URL, pei o le pusa mumu, kiliki "OK"
2. Fa'aopoopo le si'osi'omaga atina'e ESP32
3. I le faamalama o le Atinaʻe Board Manager, suʻe le ESP32, faʻapipiʻi
4. A maeʻa ona toe amataina le polokalama Arduino IDE, faʻapipiʻi laina tutusa o le laupapa atinaʻe, e pei ona faʻaalia i le
5. Filifili le masani "WiFiSan" ma faʻapipiʻi i le laupapa atinaʻe
6. A e sii maia •••••___••••• , e tatau ona e uuina le ki luga o le 3S.
7. A maeʻa le download, tatala le laina telefoni e mataʻituina ai le laina telefoni, ma o le paʻu o le 115200 ma faʻataʻitaʻi latalata WiFi masani. (Afai e le lelei le faʻamatalaga, atonu e le lava le eletise USB, e mafai ona e faʻafesoʻotaʻi se eletise 5V mai le pine 5V)

FAQ

E fa'afefea ona ou ulufale i le faiga o le download firmware?

Oomi ma uu le faamau Boot aʻo faʻafesoʻotaʻi i le telefoni faʻasolosolo mo le downloadina o firmware.

O le a le fua o le paʻu e tatau ona ou faʻaogaina mo le auina atu o poloaiga AT?

Fa'aaoga se fua faatatau o le 115200 pe a tu'uina atu fa'atonuga AT.
