Unable to communicate with Ember NCP

[alimdi]

Hi,
I'm trying to use Zigbee Sniffer on usb-ITEAD_SONOFF_Zigbee_3.0_USB_Dongle_Plus_V2_20231218195308-if00. It has been flashed with the last silicon labs firmware.

Am I doing something wrong ?

Are you compiling your self, or using a pre-compiled JAR? I see you're using a very high baud rate - I've not tested this, and I think support was only added for this by Silabs recently, so possibly you will have a newer version of EZSP and will need to update the library - depending on how/when the JAR you're using was compiled.

I'd suggest to enable debug logging if possible so we can see what is actually happening...

Hi,

Using 1.0.1 precompiled release. About the baud rate, I've used the one recommended by silicon labs after flashing the multipan rcp firmware. I've reverted back to Standard Zigbee (NCP) firmware - Baudrate 115200 and tested the pre-compiled without luck.
Setting the -s option doesn't give much info

# (c) Ember - InSight Desktop

I'll try to recompile the jar myself (any available steps to follow for that?) and make the test again.

If you have maven, and the JDK installed, then it should be as simple as running mvn clean install to build a new JAR. If needed I can build one.

Should definitely be easier for you, so thank you! Let me know if you need something on my side to do so.

I'll create a new JAR - just give me 12 or 24 hours as I'll re-release the main library as well so that it has the latest EZSP version support and this will take some hours to filter through the system...

[cdjackson]

You can find the new JAR here -:

https://github.com/zsmartsystems/com.zsmartsystems.zigbee.sniffer/releases/tag/1.0.2

This uses the latest library. Also, make sure that the correct flow control is selected - I found not much happens if the software flow control is required, and hardware is selected.

Definitely working.
Many thanks for your help !
