Closed lightsalt2011 closed 1 year ago

lightsalt2011 commented 3 years ago

we follow https://github.com/espressif/esp-iot-solution/tree/usb/add_usb_solutions/examples/usb/usb_cdc_4g_module project, build pass,

we connect CAT.1 device(EC600S-CN), but the AT fails

error log as below:

the AT command timeout, how can I fix it?

and how can I get the 4G 模组 USB CDC 输入端点 （IN）和 输出端点（OUT） 地址 ?

lightsalt2011 commented 3 years ago

another, can you provide the purchase link of "中移 ML302" , we can verify the 4G PPPoE function firstly, and then we can use EC600S-CN for production, thanks

AT command "process command timeout", due to the usb usb enumeration fail?

@lightsalt2011 error message: HCD_PIPE_EVENT_ERROR_XFER seems you are using a wrong endpoint address. About endpoint address: Please check the module's specifications to find which endpoint is used for PPP Dial, then check the address of the endpoint using lsusb -v . (You can also attach the module's specifications, etc. We will help) For ML302: You can search then purchase any ML302 develop board from taobao.com, please be careful the different sub-names of ML302, like ML302-DNLM support FDD and TDD, but ML302-CNLM only support TDD.

lsusb -v output is above message, EP IN: 0x83, EP OUT:0x0c ?

still error like use default EP address

leeebo commented 3 years ago

@lightsalt2011 Can you attach the product's specification?

lightsalt2011 commented 3 years ago

how about the spec,

achao1104 commented 3 years ago

I have the same question, is the CDC in and out same as USB PID and VID? BTW, I am using SIM7600

@lightsalt2011

lsusb -v output is above message, EP IN: 0x83, EP OUT:0x0c ? still error like use default EP address

Yes, based on the above descriptor message, the address seems like EP IN: 0x83, EP OUT:0x0c. But I found the EP MPS of that is 512, while in the demo code we default MPS=64 (USB1.1 Fullspeed mode only support MPS 64 in bulk transfer, NOT Sure if EC600S-CN only support USB2.0), you can contact 4g module vendor to check that.

P.S. You can add a USB Fullspeed isolator before the module's USB connector (force the module works in USB1.1), then check the descriptor again using lsusb -v. (Some usb device could switch descriptors in different USB speed mode, and could have different endpoint addresses).

lightsalt2011 commented 3 years ago

thanks for ur reply.

while in the demo code we default MPS=64 (USB1.1 Fullspeed mode only support MPS 64 in bulk transfer

as I known, CDC protocol be supported after USB2.0, so "USB1.1 Fullspeed mode" means USB2.0 full speed(12Mbps) USB2.0 high speed(480Mbps) ?

NOT Sure if EC600S-CN only support USB2.0

I will check with EC600S-CN vendor, but I thinks it both support

You can add a USB Full speed isolator before the module's USB connector (force the module works in USB1.1)

it is really a pity that we donot have a USB Full speed isolator device

by the way, "中移 ML302" have been booking, we will verify this function with the devices which you have verified, and then we will debug EC600S-CN for production

pls have a check if this CAT.1 you have verified or NOT, thansk https://item.taobao.com/item.htm?spm=a230r.1.14.33.70c92151IzyptY&id=613756460633&ns=1&abbucket=15#detail

leeebo commented 3 years ago
  1. USB1.1 Fullspeed mode and USB2.0 Full speed are similar, but USB1.1 Fullspeed mode and USB2.0 High speed have much more difference, The USB defines the allowable maximum bulk data payload sizes to be only 8, 16,32, or 64 bytes for full-speed endpoints and 512 bytes for high-speed endpoints. EC600S-CN CDC Data interface only has 512-bytes endpoint, which should be high-speed only.
  2. I think the ML302 module you book should work with the demo code
lightsalt2011 commented 3 years ago

thanks for ur reply, we will test when ML302 module I get.

another,

  1. when the usb_cdc_4g_module project will support USB2.0 High speed of CDC ?
  2. is there any plan that support USB CDC RNDIS protocol for esp32s2/s3 ?
leeebo commented 3 years ago
  • when the usb_cdc_4g_module project will support USB2.0 High speed of CDC ?
  • is there any plan that support USB CDC RNDIS protocol for esp32s2/s3 ?
  1. USB2.0 High speed needs different USB hardware controller, which esp32s2/s3 don't have.
  2. No USB Host RNDIS plan now, it depends on user requirements in near future. But third-party project like tinyusb have support USB Device RNDIS in esp32s2/s3.
leeebo commented 3 years ago

I have the same question, is the CDC in and out the same as USB PID and VID? BTW, I am using SIM7600

No, they are different concepts in USB specifications. IN and OUT endpoint addresses used to distinguish different functions(one device may have multi-functions and multi-endpoints) . USB PID and VID used to distinguish different devices.

use this new module https://item.taobao.com/item.htm?spm=a230r.1.14.33.70c92151IzyptY&id=613756460633&ns=1&abbucket=15#detail, we get log as below, it seems like that usb enum pass ? but I cannot visit The Internet when I connect the AP named "esp_4G_router", I am sure when I use AT cmd "AT+MPING="www.baidu.com",,1" can access the BAIDU.

  1. Please add your SIM Card Information
  2. Which device did you use for the internet, Android or IOS or PC with Windows?
  3. Did you get any error message in your browser?
  4. You can try to modify your APN (in menuconfig -> 4G Modem Configuration -> Set Modem APN) from default internet to that provided by internet operator, such as cmnet when using China Mobile.)

I refs this link https://m.c114.com.cn/w118-1127343.html use AT CMD with windows pc

It should be the DNS problem, the DNS address got from the DHCP server seems inaccessible. Temporary solution, you can fix your device's DNS address to 114.114.114.114 or 8.8.8.8 .

Will support DNS manual configuration in next commit.

without hardcode for DNS, sometimes esp32s2 can access Internet normally, but it is not stable.

  1. how can I make DATA bandwidth(upload and download) increased
  2. how can I test the DATA bandwidth performance

  1. Please update to the latest commit, optimization suggestions added in readme
  2. You can also find how to solve the esp-netif_lwip-ppp: pppos_input_tcpip failed with -1 problem in readme

thanks for ur reply, BTW, how can I test the DATA bandwidth performance

lightsalt2011 commented 3 years ago

we test with Mac OS / Windows 10 / IOS 14.6 / Android OS just Android OS can access Internet smoothly, Mac OS / Windows 10: cannot IOS 14.6: very low speed

is this issue about PPP protocol or ESP wifi functionality ?

if we use this eps32 which connected with CAT.1 to develop wifi mesh router , is it OK ?

leeebo commented 3 years ago

@leeebo how about the power consumption of CAT.1 ? if CAT.1 4G module always connect with ESP32S2 by usb. if no packet communication , CAT.1 will suspend or not ? does the protocol of USB CDC PPP can guarantee the suspend or resume ?

@lightsalt2011 Hi, we have tested the EC600 module, which works as normal now, you can pull the latest and try.

You can choose the module in menuconfig now Menuconfig → Component config → ESP-MODEM → Choose Modem Board, no need to manully config the endpoint.
