Will this problem occur when i use Gurux AMI4?

Hi,

What I see from the non-ciphered bytes is that you are sending GatewayRequest, but the GW doesn't reply GatewayResponse. GW sends PDU without this info,

Can you share the block cipher and authentication keys so I can verify this and check if this is the reason for this?

BR,
Mikko

Hi,

"The meter replies AssociationResponse without GatewayRequest" do
you mean 0xE7 00 08 76 90 50 00 00 00 00 07 prefix? if so no as i
thought the end device HES is know to the Gateway does Gurux checks this Gatewayresponse as i believe in previous version(i dont remember which) it was working fine was there an update to check this frame?

Hi,

And also can you suggest what to do when there is a need to send multiple meters data to HES at once?

Hi,

I believe that Push messages are the best option if you want to send multiple meters data to the HES.
