Tikanga Mahi
Whakaara Kōwae
Mahinga Mana-i runga i te waahanga
Ko te tikanga whawhai kōwae e whai ake nei
- Whakauruhia te USB Micro ki te hononga USB J103 (J104 ranei)
- Hurihia te whakakā SW101 ki runga ki te kaa, ka marama te LED101, LED102, me te LED103.
- Ki te rehita pai te kōwae ki te whatunga, ka pōturi te auau o te rama o LED101, ki te kore ka tere tonu te hikohiko a LED101. Ka uru te kōwae ki te aratau PSM, kei te kati ranei te kōwae, ka puta te LED101.
Ko te tikanga kati kōwae e whai ake nei:
- Hurihia te whakakā SW101 ki raro ki te ahua kore, ka kati aunoa te kōwae, ka puta atu a LED101, LED102, me LED103.
- Ka taea te whakakore i te kōwae ma te whakahau AT. I te wa e noho ana te kōwae i roto i te mana hiko, whakaurua te whakahau AT "AT+CPOF" ka mutu aunoa te kōwae. Ētahi atu kōrero. Tena koa tirohia te raupapa SIM7022 _AT whakahau.
Tāuta Atekōkiri
USB-ki-UART Tāuta Atekōkiri
Ka taea e te hononga e whai ake nei te tiki USB ki te taraiwa UART.
https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers
I muri i te whakaurunga pai o te taraiwa, ka puta te tauranga rangatū mariko e whai ake nei, COM95/COM93/COM94
Ripanga 14: USB ki UART tauranga
| Tau Tohutoro | Momo atanga | Tau tauranga | Tauranga rangatū | Whakaahuatanga mahi |
| J103 | ECI | COM93 | Whakanuia te UART | Ka whakamahia mo te whakawhitiwhiti korero AT, te tuku raraunga me te whakamohoatanga firmware |
| Sci | COM94 | UART Paerewa | / | |
| J104 | / | COM95 | USB KI UART Piriti | Whakamahia mo te DEBUG rorohiko |
Tukanga Whakapai Maama
I mua i te whakahōu i te mārō, tēnā whakapā atu ki te rōpū tautoko hangarau a SIMCom me te kaiwhakarato kia whiwhi i te taputapu tango tika me te whakamohoatanga mārō file.
Ko te tikanga whakahou firmware o te kōwae e whakaatuhia ana i raro nei
- Whakauruhia te Micro USB ki roto i te hononga USB J103 (AT/DL UART), hurihia te SW101, SW1 ki te ahua ON
- Whakatuwherahia te taputapu EiGENCOMM_MultiDownload ka whai i nga taahiraa.
(1) Tirohia te kōwhiringa "EraseALL".
(2) Tīpakohia te bootloader/system/calibration i roto i te huri, ka utaina te ipu e rite ana file.
(3) Tīpakohia te tauranga Whakarei.
(4) Paatohia te "DL" ka tatari kia murua te rorohiko.
- I ūkuia te pūmanawa.
- I muri i te whakaoti i te whakakorenga rorohiko, uru ki te atanga tango rorohiko
- I muri i te whakaurunga ki te atanga tango rorohiko, pehia te paatene "SW102" ka tatari mo te tango rorohiko.
