Cinterion Concept Board Unresponsive After Switching to SPI mode | Telit Cinterion IoT Developer Community

I already called AT^SCFG="GPIO/mode/SPI","std"
When I try to set to SPI mode, the board will only show the following and becomes unresponsive:
at^sspi=1000,0000,0000
CONNECT
On my board, I set all the DIP switches to top position except for #3 on right set of 4 switches.
Did I miss something here? Thanks.
Hello,
After connect you are in a data mode. Have you tried to send the valid messages for SPI according to the AT Commands Specification document. There are also some examples. To return to AT commands mode you need to send # character.

Thanks for the response.
There is another issue though. The commands I send cannot contain 'A6' which is a valid hex number. If I send '<000A6000015>', it will respond with a {0!0002}. If I send <00000000015>, the response is {0+}. My SPI device ***** to receive these bytes though. Did I misunderstood the command format?
Found the problem. I use a wrong format for the command. IT should contain the offset and read length before my data. It should be '<a00001000A6000015>'.
