we have tested it. It works well.

Hi,

I tried to connect USB hub. Which is detected as Unknown Manufacturer hub

where can I add the vendor ID and Device Id

Thanks in advance

Hello,

We can able to use EC25 with omega2. Currently, LTE module access single available USB port directly. I would like to know, if we expand USB ports using USB hub, Is it possible to run LTE module on emulated usb port. I am sure USB camera works. Do I need to do any configuration changes to access right USB port. if Yes how can I access configuration related to LTE.

Thanks for any help

@crispyoz Thanks, I will try.

Hi @akhileshthorat @Lazar-Demin
So far,

1. USB Detected successfully,
2. AT commands are working over /dev/ttyUSB2
   

Problem: raw ip mode is not able to enable
root@Omega-ED9D:~# o2lte data enable

Enabling LTE data connection
ifconfig: SIOCGIFFLAGS: No such device
/etc/rc.common: line 1: can't create /sys/class/net/wwan0/qmi/raw_ip: nonexistent directory
Done

does EC200 supports raw Ip mode? Am I missing anything here?

Thanks,
Naveen

@akhileshthorat USB Interface. My understanding is, the existing omega2-lte-base package uses USB. I am trying to use same.

@Lazar-Demin Thanks. I am trying to interface. I will keep you posted.

Hi,

Does any one have a idea that the existing GSM, GPS software works with EC200U-CN. Currently, I don't have any issue with EC25. Due to unavailability of stock and cost, I am planning to use EC200 as a replacement.
Thanks in advance.

Hi @Nagarjuna-Reddy
does this works with any SIMCOM module? I am trying to interface A7672 with Omega.
This PPP link works on USB or UART?
It would be great if you could write bit around the hardware.

Thanks in advance.

@Lazar-Demin Thanks. we had issue with USB detection.

Hi,

I am trying to run EG25-G on custom board. Used below method to install the LTE driver.

1. opkg install - Success
2. opkg install omega2-lte-base - Success
3. o2lte apn "www"

Setting APN to www
Done

1. o2lte data enable

Enabling LTE data connection
ifconfig: SIOCGIFFLAGS: No such device
/etc/rc.common: line 1: can't create /sys/class/net/wwan0/qmi/raw_ip: nonexistent directory
Done

Does anyone have any idea about what is going wrong. Do I need to add anything in the network config /etc/config/network

@Lazar-Demin My bad. Yes it is RAM. How can I add Swap file with SD card, I can see the document is for USB drive. is there any tutorial for it, My understanding was, we add SD card automatically swap file have been added. I see no Swap file has been created.

@crispyoz its 60kb on disk.

pip install losant-mqtt

@crispyoz Thanks for the reply. I tried still I am getting creating tempame error. Am I missing anything.

Hi,
I am keep getting Out of memory error after installing SD card of 16GB.
I followed the steps in http://docs.onion.io/omega2-docs/boot-from-external-storage.html#boot-from-external-storage-mounting-the-external-storage-device for SD card. Still I am facing issue. May I know any one encountered same issue.

Thanks,

New user, I am facing a issue using with UART lines. The problem I have observed is some unknown junk characters read by Omega 2P over UART1 lines.
I am sending UART data from STM32 with baudrate of 115200 and configures UART1 (Omega2) also 115200.
If I change baudrate to 9600 everything works perfectly.
Is there anything to do with clock speed of UART of Omega2?
What is going on in omega2p if I use 115200 baudrate.
I used python-light (python2) develop simple script to read UART1 lines. My firmware is up to date.
