Zwave Firmware update on DSGW-210-B-13

Hi,

I need to update our SDK version on the Dusun IOT GW for Z-wave, because the device I need to pair is supporting SDK 7.19.

Right now pairing is failing on Endpoint 16 (EP16 is Meter CC, scale KWh, size 2Bytes, precision 2Decimals).

Pairing is timing out on EP16. The manufacturer asked for firmware update on the controller.

Right now this is what I have in the Dusun GW:
“manufacturer”: “Silicon Labs”,
“label”: “700/800 Series”,
“description”: “USB Controller”,
“fingerprint”: {
“manufacturerId”: “0x0000”,
“productType”: “0x0004”,
“productId”: “0x0004”,
“firmwareVersion”: “7.18.1”
},

Please advise how to upgrade to 7.19.3.

Thanks,

Gyula Halmos
