EHS6 ADC - reading analog inputs | Telit Cinterion IoT Developer Community

Hi all,
In the TC65i we were able to read analog inputs using AT commands for example:
AT^SRADC=1,1,500.
To my understand in the EHS6 there is only one analog input I can read using AT commands?
I saw somthing about
Thanks
Shaul
Hi Shaul,
TC65i has to ADC channels, EHS6 one ADC channel.

So there is no way to use 2 analog inputs?
This is a quote from your concept board guide:
Dear Shaul,
EHS6 module has only one ADC channel.
The concept board has four.
So only if you are using a concept board with embedded EHS6 module you can use four. But still all of them are multiplexed to one ADC input of the module.
You can configure these four concept board inputs by a hardware switch on the concept board or CCU (by your application in runtime - see concept board HD for details).
Best regards,
Bartłomiej
Is there a way to use those 4 channels with multiplexing not on the concept board?
Hi Shaul,
You would have to develop your own hardware for your solution because the 4 ADC channels and the switching mechanism is a part of concept board. From the module perspective you only see one channel and have the AT command (or Java API) for reading this one channel.
