SNRM byte mening

Forums
Gurux.DLMS

Hi, I am newbie with DLMS. I am testing Gurux.DLMS.Python and I am working with a meter simulation software. I am able to use the Gurux.DLMS.Client.Example.python giving the command "main.py -S /dev/ttyS0 -c 16 -s 1 -a None" and the simulator works fine. When I sniff the frames, at first step the python code send the SNRM frame:

7e 0a 07 03 21 93 0f 01 7e

the simulator answers with UA response

7e a0 20 21 03 73 73 98 81 80 14 05 02 00 80 06 02 00 80 07 04 00 00 00 01 08 04 00 00 00 01 ce 6a 7e

P384 Client Certificate incorrect issuer CN

Forums
DLMSDirector

We are trying to import P384 Client Digital Signature certificate to meter and we are getting OtherReason. The reproducing steps:
1. We import successfully in meter your P384 Root CA Certificate that has CN=Root CA 384.
2. We create P384 Private key and use Get Certificate.. from context menu.
3. We select Digital Signature and enter Client System Title and create certificate.
4. In Certificate tab we use Info.. from context menu.
5. In Info window it shows that Issuer CN=Root CA 256 and this is the reason meter rejects this certificate

DLMS Stack hang during Firmware Upgrade

Forums
Gurux DLMS for ANSI C

Hi,

I am trying to update the meter firmware using GuruxDLMS.c library. I am able to establish connection with the meter in Firmware Upgrade mode. Post this, while i am trying to read Image transfer enable status, block size and image transferred block status, meter isn't responding for the one of the TX sent by stack and stack is hanging in com_read function while returning with DLMS_ERROR_CODE_RECEIVE_FAILED error.

Request you let me know what could be the reason.

Please find below details for your analysis.

Itron SL7000 load profile return error

Forums
Gurux DLMS for ANSI C

Hi Mikko, i am back working on the itron meter data reading. I created new forum post because i can't reply on the old one. 
After trying out the update, the issue on reading Itron SL7000's load profile (0.0.99.1.0.255) still persists
- if i read capture objects first (index 3), it returns error 13 : DLMS_ERROR_CODE_ACCESS_VIOLATED
- if i read without it, it returns error 258 : DLMS_ERROR_CODE_INVALID_PARAMETER, but i can see some data in the traces, and i can use GXDLMSTranslator to translate and get the data
