Hii Sir,

With the updated gurux i am not able to remove any certificate from the meter.

while testing i found that the gurux sending wrong serial number (inverse direction) of the certificate for remove certificate method.

E.g:
Actual Serial Number of the certificate
Decimal = > 1001562
Hex = > 0x0f 48 5a

03 0f 48 5a == > for export certificate => gurux certificate number received from gurux by serial number

03 5a 48 0f == > for remove certificate => remove gurux root certificate serial number received from gurux by serial number
