4G Router using SIM7600 and ESP Wroom32 #26

Open RenjithBeginow opened 1 year ago

RenjithBeginow commented 1 year ago

Hi myself Renjith. I am trying to set a 4G router using SIM7600 and ESPwroom32. I have configured the details using menuconfig, but Iam getting an error and ESP is getting force restart.

I (62639) bridge_modem: Modem PPP Started I (62734) bridge_modem: IP event! 6 I (62735) esp-netif_lwip-ppp: Connected I (62735) bridge_modem: Modem Connected to PPP Server I (62738) bridge_modem: ppp ip: 25.43.7.145, mask: 255.255.255.255, gw: 10.64.64.64 I (62747) bridge_modem: Main DNS: 49.45.0.1 I (62752) bridge_modem: Backup DNS: 0.0.0.0 E (62758) bridge_modem: PPP netif event = 0 E (62761) bridge_modem: Just Force restart!

Please help me to sort it out.

Hi @RenjithBeginow What is the version of idf you are using, you can delete this esp_restart() first, this will not be affected.

RenjithBeginow commented 1 year ago

Hi tswen, IDF version ESP-IDF v5.1-dev-1626-g4b6d9c8ad3-dirty, OK let me try by deleting the esp_restart()

tswen commented 1 year ago

If you will only use a data forwarding netif, such as softap, it is recommended that you use idf release/4.4

RenjithBeginow commented 1 year ago

Hi, After deleting the esp_restart() function, I am able to connect device to the softAP of ESP and the device is getting internet now. But I have noticed that the speed is too too slow, is there anything i have to do in the code, also when i debug with the serial port of the ESP is giving result many times. W (857566) esp-modem-dte: Rx Break Is it due to the buffer size or something like that?

tswen commented 1 year ago

It is recommended that you use idf release/v4.4 first, because idf release/v4.4 has been verified by many customers, and the throughput depends on the baud rate of uart. If you want to get higher throughput, it is recommended to use ESP32-S3 + 4G (USB interface)

RenjithBeginow commented 1 year ago

Thanks for the support tswen. Let me try with idf release4.4 and I will let you know the feed back.

RenjithBeginow commented 1 year ago

Hi, I have tried with release/v4.4.3, Iam getting internet but the speed is only almost 15-20Kbps. Also Iam getting this return frequently while trying to connect with internet. esp-modem-dte: Rx Break

RenjithBeginow commented 1 year ago

Hi Tswen, Can I have your mail ID?

tswen commented 1 year ago

This communication rate depends on your uart baud rate, if you need high throughput, it is recommended to use the usb interface

RenjithBeginow commented 1 year ago

Hi Tswen, Can you help me to implement with USB, I have ESP32S3 and SIMCOM A7600 modem. While communicating with USB its showing waiting for USB port, while connecting A7600 to PC it will show 4USB ports, so will I have to do anything in the ESP32 code to tell ESP that this is the port.

tswen commented 1 year ago

If you only need to implement 4G -> AP, it is recommended that you use this demo , Is it because the 4G module has insufficient power supply that the usb connection is not detected?

RenjithBeginow commented 1 year ago

Hi, Iam getting debug result as given below, and its not going forward. Waiting

tswen commented 1 year ago

The program running here means that the usb host has been initialized and is waiting for the connection of the usb device. If it is not confirmed that the usb has been inserted, please confirm whether the modem module is reset in time, or whether the power supply to the 4G module is abnormal.

Also when I connect the gsm module reset to ny IO the modem is not at all getting ON, So I have only given the powerkey pin. After modem is getting ON I will start the ESP32, is there any problem by doing this.

RenjithBeginow commented 1 year ago

Hi, Is there anything else i need to do or taken care in order to enable USB. I have checked power supply and the USB cable iam using, but still its not moving further. Still getting the same output.

leeebo commented 1 year ago

Hi @RenjithBeginow, the log shows no device appears, please double check your hardware connection, if you just insert a USB disk, can it goes further?

RenjithBeginow commented 1 year ago

Thanks leebo, I will check and let you know.

RenjithBeginow commented 1 year ago

Hi leeebo, As u said I have tried with a USB drive connected to the usb port of esp32s3, but still its not proceeding to further. Its waiting "ESP_USBH: Port power: ON Succeed" here itself.

RenjithBeginow commented 1 year ago

Hi, Can u help to sort it out. I have got stuck here.

RenjithBeginow commented 1 year ago

Hi @leeebo leeebo & @tswen , Please help for the development.

leeebo commented 1 year ago

@RenjithBeginow Hi, if the USB drive can not be detected also, the most likely issue is the power supply. Which development board do you use? Does the USB interface have reliable 5V output?

RenjithBeginow commented 1 year ago

Iam using esp32s3 development board. Modem I have a 3A power supply and for esp currently Iam powering up with usb power.

RenjithBeginow commented 1 year ago

Hi, I have made the power of ESP also from a 5v power supply to esp32s3, still the program is waiting there itself, i am not able to debug the problem.

m5it commented 1 year ago

you achieve to connect to device and upload you sketch or binary or your program you are trying to run? maybe you need to hold down boot button until it get connected? try another esp32 and another cable. port is correct? /dev/ttyXXX ? :) try build and upload some simple example like hello world first.

RenjithBeginow commented 1 year ago

Hi @m5it, Its not like that, iam able to upload and communicate with esp32s3. My problem is I have connected the ESP32S3 with SIM7600 via USB communication(Note: Not the uart to USB, hardware USB port of ESP32S3). But its getting stuck at some point. So when I asked, in the previous chat i was told to try to connect a USB pen drive to check whether is it showing anything else. I want to know whether I need to do any configuration in order for the USB port need to work.
