SPI problems on the Concept Board (EHS6) | Thales IoT Developer Community

October 16, 2015 - 3:54pm, 3201 views

Hi Gemalto,,,

I can't get SPI to work on the Concept Board with AT commands or from Java.

Here's what I've done:

1. On the 'right-hand' switchbank (The one that has only 4 switches), I have switch 3 low and switch 4 high. According to the 'Concept_Board_Hardware_Interface_Description.pdf' page 13, this will send all the SPI signals to the shield interface (That's where I am looking for data output or at least a clock output).

2. Here's basically my java code:

try {

SpiConnection spiConn = (SpiConnection)"spi:0;baudrate=100;clockMode=1");

int baudrate = spiConn.getBaudRate();

InputStream inStream  = spiConn.openInputStream();

OutputStream outStream = spiConn.openOutputStream();


while (true) {


System.out.println("Sending Spi again...");


try {


} catch (InterruptedException e) {

// TODO Auto-generated catch block




String data = "<dummy>";

outStream.write(data.getBytes(), 0, data.length());




catch (Exception e) {System.out.println(e);}

I expect to measure some data or clock signals on the SPI output on the shield interface (labelled 'SCK' and 'MOSI' on the concept board). I don't have a slave connected, but I assume it should work anyway.

3. I've tried to use the AT command 'AT^SCFG="Gpio/****/SPI","std" and I get the 'OK' response. My AT^SCFG? is pasted below:


^SCFG: "Call/ECC","0"

^SCFG: "Gpio/****/ASC1","rsv"

4. My AT^SSPI? output only produces the following: '+CME ERROR: Unknown'.

Thanks for reading and please let me know if you have any advice.
