EHS5-E rev.4 - GSM call problems | Telit Cinterion IoT Developer Community

February 28, 2019 - 3:09pm, 4625 views

Hello,

We have bought some EHS5-E devices, and surprisingly they don't have onboard as usual a fw version = 3.001 but instead they have a fw version = 4.x.

The response to the command ATI1 is the following:

Cinterion

EHS5-E

REVISION 04.000

A-REVISION 01.000.01

OK

The problem is that if we try to make a GSM call versus the device, it does not work as it do in fw. 3.001 versions.

Also, there is no documentation or SDK available for this 4.000 revision !!!

Someone could help me?
