[Solve] [EHS6] Wrong answer format when "RING" and "ATV0" | Telit Cinterion IoT Developer Community

September 27, 2017 - 4:59pm, 2834 views

Hello,

We have notice that the EHS6 with firmware version 3.001, is not sending correct answer on serial in this case :

1/ Set "ATV0" to the modem in order to get short answer response.

2/ Make a call to the EHS6 and wait for RING information. RING shortcode is "2".

3/ Output on the serial link is : <CR><LF>2<CR><LF>

This is wrong.

According AT command guide (Chapter 2.5) the output must be : <numeric code><CR>

Furthermore, we have tested with different chipset (BGS5, and old TC65i) and they are working well, as expected.

Is this a bug in EHS6 firmware ?

This is very important for us, in order to upgrade old modem to this new one, without rewritting any line of code (this is not possible due to large amount of system everywhere in the world).

Thank you for your feedback.
