Hi there,
My configuration includes Connex (version J, no Bluetooth module)
together with GPSstix and CFstixwith 512 MB Sandisk CF. I'm succesfully
using the FFUART to log into the gumstix from my linux laptop with
kermit, through a serial to USB converter from FTDI.
The gumstix is as it came out of the factory, no reflash, not even tried
to run the hello world program.
Also, I'd like to leave the FFUART to be the console.
I'm trying to use the BTUART of my gumstix (exposed on the GPSstix) to
connect to another serial to USB converter from FTDI attached to another
USB port of my laptop. I'd like to do some preliminary programming
experiments like sending and receiving simple characters over the BTUART
to and from my laptop.
The physical connection is as follows: (it works for the FFUART)
GPSstix BTUART FTDI USB converter
TxD-------------------------------------RX
RxD-------------------------------------TX
GND------------------------------------GND
Once logged into the gumstix I issued the following commands: (as
suggested by Defy on http://www.pegasushabproject.org.uk/pegasus3.html)
/stty -F /dev/ttyS1 speed 57600
(obviously configured kermit on my laptop for speed 57600)
/
echo some text > /dev/ttyS1
(should send the string "some text" to the BTUART)
My problem is that the instance of kermit which looks after the USB
converter connected to the BTUART waits there and the cursor does nothing.
Instead, I expected to see the string "some text" appear...
I tried different speeds including 57600
Also the FTDI USB to serial converter works
An additional clue is that my gumstix, during boot time looks for the
bluetooth module, and can't find it as it is not there. However, again,
I expected to see those data sent to the non-present bluetooth
module...but no luck
I'm clearly missing something, so in conclusion, can anybody suggest a
possible solution? Thanks (also for reading this lenghty email! ; ) )
(almost) Happy New Year
Luca
