EHS6T, what changed from revision 03.001 to 04.013? | Telit Cinterion IoT Developer Community

Hi
We previously used EHS6T with rev. 03.001 but now received EHS6Ts with 04.013. What are the differences? Power-up seems to have changed (takes longer to reply to "AT" through RS232), also seems to take longer to find network. Can you please give me some information about what has changed? Also, if the newer version is not good for us, how can I change them back to 03.001?

Hello,
Revision 4 modules have some small hardware changes and therefore it is not possible to install revision 3 firmware on revision 4 module and vice versa.
From the functional level both are generally more or less the same. Of course it is a new firmware revision so there are some small changes/updates or fixes inside. But we probably don't have any document listing every difference.
Best regards,

Hi,
I think you should provide documentation about the differences. One thing I found is as follows:
I am using RS232 and I measured the ***** from powerup to SYSLOADING and SYSSTART. For Rel3 the ***** are:
The same ***** for Rel4 are:
I am now trying to test everything to see if Rel 4 works in our system. So, a document of the differences would be nice.

Hello,
Here you can find the release note for 04.003 in comparison to revision 03.001:
https://iot-developer.thalesgroup.com/documentation/download-documentati...
We probably don't have more detailed document now.
I have found the following note there "The module startup until SYSSTART takes 5 seconds longer compared to previous release." in "Known Issues" chapter.
Best regards,
