NCP requires unsupported version of EZSP

[axoduss]

Hi,
I'm trying to use Zigbee Sniffer on usb sonoff Dongle Lite MG21. It has been flashed with the last firmware.

java -jar ZigBeeSniffer.jar -port /dev/ttyUSB0 -baud 115200 -flow software

Am I doing something wrong ?

Z-Smart Systems Ember Packet Sniffer
NCP initialisation starting...
Opened serial port /dev/ttyUSB0 at 115200
[main] ERROR com.zsmartsystems.zigbee.dongle.ember.ZigBeeDongleEzsp - EZSP Dongle: NCP requires unsupported version of EZSP (NCP = V14, supported = V4-V13)
Unable to communicate with Ember NCP
[main] INFO com.zsmartsystems.zigbee.serial.ZigBeeSerialPort - Serial port '/dev/ttyUSB0' closed.

thank you

Currently the latest firmware is not supported. This will be added "soon" (it's being worked on) but you should use V7 instead of V8 (which is the latest).
