is it possible to use EC200U GSM module instead of EC25 with omega2+
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.
@naveen_kumar definitely possible, but it's likely that you'll have to make slight adjustments to the software and/or configs
@Lazar-Demin Thanks. I am trying to interface. I will keep you posted.
Hi @naveen_kumar ,
I believe we can interface EC200 with Omega using USB Interface. Quectel provides a application note for building Linux Drivers on Windows and Linux.
How are you trying to interface the GPRS module? through pppd over uart or usb interface?
@akhileshthorat USB Interface. My understanding is, the existing omega2-lte-base package uses USB. I am trying to use same.
- USB Detected successfully,
- 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
does EC200 supports raw Ip mode? Am I missing anything here?
I believe o2lte-base package is meant for Qualcomm based LTE-Cat4 cellular modem specifically for Quectel.
EC200 is LTE-Cat1 and it doesn't use Qualcomm processor, rather different processor.
The logs you got for enabling data connection mentions qmi tool , which is only applicable for Qualcomm. qmi won't work for EC200UCN
Need to build drivers for EC200
I have been working on similar modem for SIMCOM7672 LTE-Cat-1 module over USB. But I haven't able to get USB detected on Onion2.

@crispyoz Thanks, I will try.
