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.
