CC2540 with Terminal/Matlab

Other Parts Discussed in Thread: CC2540

Hi,

Im trying to use Terminal to communicate with the CC2540, and i used the code provided from btool to send the hex files.

For example to initiate de Gap_Device in BTool i get this:

[2] : <Tx> -
-Type : 0x01 (Command)
-Opcode : 0xFE00 (GAP_DeviceInit)
-Data Length : 0x26 (38) byte(s)
ProfileRole : 0x08 ( Central )
MaxScanRsps : 0x05 (5)
IRK : 00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00
CSRK : 00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00
SignCounter : 0x00000001 (1)
Dump(Tx):
01 00 FE 26 08 05 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 01 00 00 00

So i send the "01 00 FE 26 08 05 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 01 00 00 00" in Terminal to the device but i don't get any answer.

It would be great if someone could help me and explain what am i doing wrong.

Thanks

Hi Fernando,

Have you made sure that the port has been successfully opened to the CC2540? It should answer even if it understands you or not. Also make sure that the format is correct (i.e. sending in hex/binary etc.).

The port is connected and what i'm sendind it's equal from the btool log. Here's the image with what i send:

I'm not sure what that tool transmits, it could be that it transmits the spaces (and end line) as hex representation or something like that. Are you able to sniff the serial line, or maybe set breakpoint in HostTestRelease (On C2540 Dongle) during debug mode?
