Hii,

I want to import the certificate in meter with action with block transfer method but gurux always requested with segmentation i.e 0xA8 event if meter negotiate conformance with action with block transfer.

Tx/Rx buffere size negotiated : 150 bytes
Negotiated conformance : GeneralBlockTransfer, BlockTransferWithGetOrRead, BlockTransferWithSetOrWrite, BlockTransferWithAction, DataNotification, Get, Set, SelectiveAccess, Action

My queries are:
1. How to do setting by which gurux will initiated action with block transfer?
2. can please provide Examples of segmentation request/response frames one for each i.e get,set,action

Best Regars,

Hi,

THis should work but I can test this. What are your PDU sizes and HDLC frame sizes?

Hi,

This is checked and it works without problems. Make sure that GeneralBlockTransfer is enabled on the client and the server-side. You can see Negotiated conformance if you select the meter and establish the connection to the meter. If GeneralBlockTransfer is not Negotiated, it's not used.

Hii,

Good Morning!!!

GeneralBlock transfer is enabled on both sides, even if gurux requested with segmentation frame type for import certificate method with buffer size 150.

Following are the proposed and negotiated conformance:
Proposed:
GeneralProtection, GeneralBlockTransfer, BlockTransferWithGetOrRead, BlockTransferWithSetOrWrite, BlockTransferWithAction, MultipleReferences, Access, Get, Set, SelectiveAccess, Action

Negotiated:
GeneralBlockTransfer, BlockTransferWithGetOrRead, BlockTransferWithSetOrWrite, BlockTransferWithAction, DataNotification, Get, Set, SelectiveAccess, Action
