Hi everyone!

I've got a problem, i need to send several bytes from PC to keyfob. Which is the best form to do it?

More precisely i'm doing a simple protocol for the lost packets.

So i need to communicate from the app of PC to the keyfob which packets are lost.

Any help is welcome...

Thanks again in advance...

Best regards,

Hi Martin,

Take a look at this thread: http://e2e.ti.com/support/low_power_rf/f/538/t/116938.aspx#415216.

There are also more threads if you search a bit :)

Thanks Nick, but that's not my problem... I need send data (several bytes) from my app in the PC to keyFob through bluetooth connection. For example to send data from the keyfob to my app in the pc i could use GATT_Notification/GATT_Indication commands. But in reverse how could i do it?

Hi Martin,

Sorry for the misunderstanding. Assuming you use our CC2540 Dongle you can have a look at BTools "Adv.Commands" tab. Under GATT youll find the ATT_writeReq command which you can use. At http://processors.wiki.ti.com/index.php/Category:BluetoothLE you'll find some PC/Linux examples if you want to do this in your own application (instead of BTool), especially the health demo which is based on the BTool PC Application.

Did I get you right this time?
