NCP requires unsupported version of EZSP

[Mallik-Tarigopula]

I am running NCP on MGM210PA32 Module from Silabs. I have connected NCP to my PC over UART. Below is the log when I run my .Net application. I got an error "NCP requires unsupported version of EZSP". I did not find any option in simplicity studio to change the version of NCP. Can you please guide me how to resolve this issue. Any changes on .Net code will resolve this issue?

Hi @Mallik-Tarigopula,
did you solve this? Got the same issue with a Sonoff Zigbee 3.0 USB Dongle Plus v2.
Regards,
Stefan

any update?
got the same issue :-(

any update? got the same issue :-(

I got rid of my issue. I guess by updating the dongle and also Zigbee2MQTT to the latest firmware version. But not sure, it‘s a long time ago.

What hardware do you use, @amosrohe ?

hi
I am using the ZB-GW04 (v1.2)
updating the firmware will only change the "required" (to V13) how did you change the supported ( supported = V4)
I am referring to the "zigbeeNet" not "Zigbee2MQTT"

tnx Amos

I got past this error by manually setting the version: EzspFrame.SetEzspVersion(7);
7 appears to be the max version this library supports, though. I now get an IndexOutOfRangeException after it connects.

hi
I also tried to change the restriction in the code and during debugging, but it raised other issues (understandable since it is a different protocol version )
