Tafura 9: switch uye mabhatani

Number	Zita	Tsanangudzo
SW101	POWER_KEY	EVB simba chinja
SW102	RESET	Module reset bhatani
SW103	MUKA	Module yekumutsa bhatani
SW1	DOWNLOAD	Firmware upgrade switch

Kana serial port baud rate iri pasi kana kuenzana ne9600bps, hapana chikonzero chekushandisa WAKEUP bhatani reEVB kumuka, uye module inogona kumutswa zvakananga nekutumira AT mirairo kuburikidza neUART1. Kana iyo baud rate yakakura kupfuura 9600bps, unofanirwa kushandisa WAKEUP bhatani kudonhedza pasi WAKEUP kumutsa module. Kuti uwane rumwe ruzivo, ndapota tarisa kune gwaro [1].

1. Kune mabasa ane hukama epini yega yega yemodule, ndapota tarisa kune gwaro [1]

Operation Method

Module Boot

Module Simba-paKushanda

Iyo module boot nzira ndeyotevera

1. Isa iyo Micro USB mu USB yekubatanidza J103 (kana J104)
2. Shandura switch SW101 kumusoro kune iyo nyika, uye LED101, LED102, uye LED103 ichavhenekera.
3. Kana iyo module yakabudirira kunyoreswa kune network, iyo inopenya frequency ye LED101 inononoka, kana zvisina kudaro LED101 icharamba ichipenya nekukurumidza. Kana iyo module ichipinda muPSM modhi kana iyo module iri mukuvhara, LED101 ichabuda.

Iyo module yekudzima nzira ndeyekutevera:

1. Shandura switch SW101 pasi kune iyo off state, iyo module inodzima otomatiki, uye LED101, LED102, uye LED103 ichabuda.
2. Iyo module inogona kudzimwa neiyo AT command. Kana iyo module iri musimba-panyika, isa iyo AT command "AT + CPOF" uye module inodzima otomatiki. Mamwe mashoko. Ndokumbira utarise kune SIM7022 series _AT command.

Kuiswa kwemutyairi

USB-ku-UART Driver Installation

Kubatana kunotevera kunogona kuwana iyo USB kune UART mutyairi.

https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers

Mushure mekunge mutyairi aiswa zvinobudirira, inotevera chaiyo serial port ichaonekwa, COM95/COM93/COM94

Tafura 14: USB kune UART ports

Reference Number	Interface type	Port nhamba	Serial port	Tsanangudzo yebasa
J103	ECI	COM93	Wedzera UART	Inoshandiswa kuAT kutaurirana, kutumira data uye firmware upgrade
	SCI	COM94	Standard UART	/
J104	/	COM95	USB KUTI UART Bridge	Inoshandiswa kune software DEBUG

Firmware Upgrade Process

Usati wagadzirisa firmware, ndapota taura neSIMCom tekinoroji yekutsigira timu uye mutengesi kuti awane chaiyo yekurodha chishandiso uye firmware upgrade. file.

Iyo firmware yekuvandudza nzira yemodule inoratidzwa pazasi

1. Isa Micro USB muUSB yekubatanidza J103 (AT/DL UART), simudza SW101, SW1 kuenda ON state
   
2. Vhura iyo EiGENCOMM_MultiDownload chishandiso uye tevera matanho.
   (1) Tarisa iyo "EraseALL" sarudzo.
   (2) Sarudza bootloader/system/calibration wobva waisa bhini rinoenderana file.
   (3) Sarudza Enhanced port.
   (4) Dzvanya "DL" uye mirira kuti software ibviswe.
   
3. Yakadzima software.
   
4. After completing the software erasing, enter the software download interface
   
5. Mushure mekupinda iyo software yekudhawunirodha interface, tinya "SW102" bhatani uye mirira kuti software itore.
