Facing issue with example

[ngoyal16]

Not able to get data when using NewSettingsWithLowAuthentication or NewSettingsWithLowAuthenticationAndCiphering

panic: error sending AARQ: error sending: read failed: EOF

[jduranf]

@ngoyal16 seems the device isn't replying the AARQ.

The issue is in this line, when the library expects the device reply, but doesn't have any reply. You should check why the device doesn't reply.

[ngoyal16]

@jduranf device is replying when there is no auth. but as soon as auth added it start thorwing the error.

/reopen

@ngoyal16 the device isn't replying, for any reason. Can you attach the sent frame using gosem library, and the expected frame by the device?

[ngoyal16]

how would i know what would be the expected frame?

[jduranf]

how would I know why the device doesn't reply? you can use another DLMS software and capture the frames

Also do we have plan to add Release request feature? while disconnect

[jduranf]

@ngoyal16 what do you mean with Release request feature? After disconnect there is nothing else to do...

Regarding the attached frames, can you send the frames using NewSettingsWithLowAuthentication?

Using NewSettingsWithLowAuthenticationAndCiphering the frames aren't the same probably due Ciphering settings. If you want, you can check generateUserInformation function, specially getInitiateRequest function to see if there is something wrong, or just review you Ciphering settings.

@jduranf release request mean RLRQ and RLRE
