Hi. I am not aware of how to remove ciphering.
This is the blockcipher key "1234567812345678"
Or can you tell me how to do that.

If you select Pdu and Comments from Trace menu in GXDLMSDirector you can see data without ciphering.

Okay. I will do this and send you the logs.
I have one more doubt regarding this. Currently image transfer happening. But its taking 10- 15 minutes through GPRS connection(Serial communication-GXDLMSDirecter also taking long time.)
Is there any solution to reduce the transfer time ?

Hi,

Hi,

Updating the image might take a long time and it's causing problems when you are communicating over the air. Is sending the image taking more time or verifying the image?

A verifying image might take a long time with some meters. Ig image size is huge, there is no easy way to improve the performance.

BR,
Mikko
