EC25 FC20 AT+QWIFI Issue

AT+QWWAN? return 0, but i am using internet with USB and its working fine. As i wrote before, WiFi and USB internet are not working simultaneously but working one at a time. I think there is no problem with hardware right now.

Dear Aamirniaz434,
Please check the following test picture in my side. Thanks!
The following is screenshot of my PC, my PC connect to module to access the network with USB NDIS network card.


The following is the screen of my cell phone, which connect to FC20 wifi to access the network.

So please confirm your test method in your side. Thanks!
By the way, if your PC connect to wifi or USB, of course it cannot support to access internet simultaneously. Thanks!

Let me re explain to you.
Step 1: I attached my hardware to computer and it can connect to computer and i can use internet over USB


Step 2 :Then I issue AT+QWIFI and AT+QWBCAST command and it executed successfully
Step 3 : When i connect my mobile to Wireless Hotspot, it can connect to WiFi but no internet over WiFi. So there is only internet over USB.

To use internet over WiFi, I need to disable internet over USB
After that i can use internet with WiFi.

So I want to use internet over USB and WiFi together. So my question was if Quectel modem can support that or why i am facing this problem.

Looking forward for your response.

Dear Aamirniaz,

I am using Revision: EG25GGBR07A07M2G. waiting for your response and fix. Normal phones can support both USB tethering and WiFi Hotspot at the same time. I think probably you need to enable it in the software and it should work.

Looking forward to hear from you. Thanks

Dear Aamirniaz434,
I have check the issue with RD, and already get the solution. Please check the following method to solve your issue. I have test it in my side. Thanks!
1.Please use the AT+CGDCONT to set the APN for context 3, the following is the example:

2.Please use AT+CGDCONT? to check all the context setting. Please make sure the contxt 1 and 3 use the different APN and the two APN are all correct of the SIM card you used.

3. Then enable WIFI function with command AT+QWIFI=1,1,3.
4. You can use the AT+CGPADDR to check whether the context 1 and 3 already obtain IP address. Please note that only them can obtained the IP normally, then you can use WIFI and USB ethernet to access the network simultaneously.

5. After that you can try to use internet over USB and WiFi together.
Hopefully the above method can help you solve the issue. Thanks!

Can quectel ec25 be programmed without using another controller?
can i see an example of wiring diagram?

Dear Sir,
Thanks for your inquiry in Quectel forum.
Yes, EC25 can be programmed. We named Quecopen solution, when you use it, you do not need to use another external controller. Thanks!
But if you want to use it, please contact our local FAE or sales, it need get the sales permission, then FAE can release the document and SDK package to you. You can email to support@quectel.com. Thanks!
The following is the brief introduction about Quecopen solution, you can have a look first. Thanks!

Hello,

We seem to be having the same issue of not being able to use WiFi and ethernet over USB for the MCU at the same time. Our MCU is running embedded linux, and we either run quectelCM and get internet over USB but no internet over WiFi or stop running quectelCM and get no internet over USB but internet over WiFi.

We tried following the instructions posted above but context 3 doesn’t seem to be able to obtain an IP address - AT+CGPADDR always shows context 3 with IP address 0.0.0.0.

Also, what does AT+QWIFI=1,1,3 do? The documentation for EC2x_WiFi_Application says the arg for AT+QWIFI= should be either 1 or 0 only.

Currently testing this in Singapore with a Starhub SIM. Below are the outputs of the relevant AT commands

AT+CGDCONT?

+CGDCONT: 1,"IP","shwap","0.0.0.0",0,0,0,0
+CGDCONT: 3,"IP","shwapint","0.0.0.0",0,0,0,0

OK


AT+CGPADDR

+CGPADDR: 1,"10.234.105.62"
+CGPADDR: 3,"0.0.0.0"

OK

Thank you

Dear Hanyang,

Also, what does AT+QWIFI=1,1,3 do?
[A]This command is to set enable WIFI function, which use context 3. Thanks!
