hello
EC200N-CN is responding to commands received with navigator software but not responding to AT commands received with esp32.
i will share my schamatic diagram below:
Main.pdf (332.7 KB)
Is ESP32 running Linux OS?
Could you show the result of
cat /sys/kernel/debug/usb/devices
yes i m using linux.
i am running { cat /sys/kernal/debug/usb/devices }command in terminal then i get output.
i will share this pic.
Please switch to root.
I cannot see it.
So there should be some problem with hardware.
If the EC200N-CN is enumerated, you can see it in “lsusb” and “cat /sys/kernel/debug/usb/devices”
sir i am not getting any output from 2C7C.
but responding to EC200N-CN AT command from the Qnavigator software.
This seems to be the hardware issue.
You can check the kernel log, there might be usb enumeration related logs.
You can repost the topic. Some one specialized at HW might answer your question.
You can see 3 /dev/ttyUSBx and network interface usb0.
