How to set up SIM7600 modem via ESP32S3 USB Port.

IDF Version: 5.0.0 ESP IoT Solution Version: Master Branch

Just selected user defined modem board in the component config -> usb host modm.

Serial Logs:

Ya that sit, it is hanged there. I guess it is wating for usb device.

Any help will be appreciated :)

@mayankbytebeam Which development board do you use? Please make sure the device is powered

narangmayank commented 1 year ago

@leeebo I used ESP32S3 DevKitC1 and SIM7600 module in this setup.

leeebo commented 1 year ago

@mayankbytebeam ESP32S3 DevKitC1 USB Port can not output 5V power.

@leeebo ok now I've powered the modem board exrternally but still some error is coming

I've selected the modem baord as user defined. can you tell me if any additional configurations is required for setting this example for SIM7600 modem?

leeebo commented 1 year ago

@mayankbytebeam 4G modules generally have multiple interfaces, of which only one is the Modem interface, it seems 0x01 0x81 corresponding interface is not, you need to try other interfaces. In my experience, it's often the second-to-last interface

leeebo commented 1 year ago

@mayankbytebeam If you don't know how to find the endpoint address of the interface, please attach your full log here, i will help

narangmayank commented 1 year ago

@leeebo sorry for the delay, we have changed the design a bit. Now we are using the N706 modem instead of SIM7600.

@mayankbytebeam From the module's descriptor, which has eight CDC-like interfaces, please first test with the penultimate one (IN 0x88, OUT 0x07). If that does not work, please try the eight interfaces one by one

Hi,

I m facing the same issue. Hardware - ESP32 S2 WROOM 1 Modem - User Defined ( NEOWAY N58 )

@leeebo which interface class's endpoints should i use from below -

@mayankbytebeam - Any Solution You Found ?

narangmayank commented 1 year ago

@leeebo Thanks for your input. 0x85 and 0x04 worked for me.
@lovepreethitech Try each end point one by one.

lovepreethitech commented 1 year ago

Hi @mayankbytebeam ,

I guess you are using NEOWAY module. I am using NEOWAY N58.

I have tried all the EPs Majority interfaces gives - AT command Timeout and 2 interfaces gives - AT&W failed error

EP IN | EP OUT | ERROR 81 | 1 | AT COMMAND – TIMEOUT 83 | 2 | AT&W COMMAND FAILED – ERROR 84 | 3 | AT COMMAND – TIMEOUT 85 | 4 | AT&W COMMAND FAILED – ERROR 86 | 5 | AT COMMAND – TIMEOUT 87 | 6 | AT COMMAND – TIMEOUT 88 | 7 | AT COMMAND – TIMEOUT 89 | 8 | AT COMMAND – TIMEOUT

Have you faced anything like this while working ?

leeebo commented 1 year ago

@lovepreethitech Hi please link Reset Control IO to your modem Reset Pin, try it again

lovepreethitech commented 1 year ago

Hi @leeebo

Could you please share the AT commands list that ESP send to 4G modem. Because my module is unresponsive to some commands. If i get the list i could check if that is working or not.

And Yes i have connected the modem reset pin to ESP.

leeebo commented 1 year ago

@lovepreethitech Hi, please set the ESP_LOG level to verbose to find the detailed Interaction process

narangmayank commented 1 year ago

@lovepreethitech Can you try commenting the command that is stucking?

Edit : I faced the same issue and after commenting the stuck command it went ahead and connected to my application server.

lovepreethitech commented 1 year ago

@mayankbytebeam In which file you comment that ?

narangmayank commented 1 year ago

@lovepreethitech

It's in iot_usbh_modem component,

@mayankbytebeam Which development board do you use? Please make sure the device is powered

esp32s3 （合宙 luatos.com） and air780e 4G

Maybe some of the environment dependencies weren't introduced correctly, I've solved my problem and it looks similar to yours

Hello, I used Lexin's esp32s3 DevKitC1 development board and Heju's AIR780E for USB host communication, but there were errors and timeout issues related to the ESP32-S3 modem module. What is the reason for this? I cannot find a solution。Here is my output log I (43) boot: ESP-IDF v4.4.4-dirty 2nd stage bootloader I (43) boot: compile time 12:18:19 I (43) boot: chip revision: v0.1 I (45) boot_comm: chip revision: 1, min. bootloader chip revision: 0 I (52) qio_mode: Enabling default flash chip QIO I (58) boot.esp32s3: Boot SPI Speed : 80MHz I (63) boot.esp32s3: SPI Mode : QIO I (67) boot.esp32s3: SPI Flash Size : 8MB I (72) boot: Enabling RNG early entropy source...

@Y1hsiaochunnn I can use the code from the Gitee library normally and have added the AIR780E option, which is convenient for me to apply to projects。https://gitee.com/dog_who_loves_cat_mint/esp32_-cdc_4-g
