Hostname size limitation on EG25-G

IoT Modules LTE Standard Module

I have problem with long hostnames. It seems the problem occurs when hostname exceeds 40 characters. When I try to open SSL with long host name I get an error:

AT+QSSLOPEN=1,1,0,"aaaaaaaaaaaaaaaaaaaaaaaaaaaa.example.net",8883
ERROR

but with slightly shorter hostname it works

AT+QSSLOPEN=1,1,0,"aaaaaaaaaaaaaaaaaaaaaaaaaaa.example.net",8883
OK
+QSSLOPEN: 0,565 - expected error the host name does not exists

AT+GMR
EG25GGBR07A07M2G

Is there some maximum hostname length? And is there some way around it?

I tried it also on EC21 module and even longer hostnames work fine there.

Hi @vladimir1
I checked version R07A08 to optimize this part.
“Increase the length of domain name returned by AT+QSSLOPEN from 40 bytes to 256 bytes.”
If you need the latest firmware, please give me your email and I will send it to you. However, it should be noted that the latest firmware has the rollback function. After the upgrade, the old firmware cannot be rolled back.
Best Regards.
