BOOSTXL-CC2650MA: HID is compatible with CC2650? How send descriptors?

Part Number: BOOSTXL-CC2650MA
Other Parts Discussed in Thread: CC2650, ENERGIA

Hi,

I have started to work with embedded systems (with TI devices) and I would like to make a Mouse/Keyboard using MSP432, CC2650 and Educational MKII.

As I have never worked with embedded systems (and low level), I'm starting with Energia with the BLE library although I think my problem is the same for CCS.

My concern is about how I can fill Gatt's Descriptor, in concrete the Report Reference Descritpor for HID devices

I have been reviewing that my bluetooth module is using the SNP: https://processors.wiki.ti.com/images/8/8a/CC2640_Simple_Network_Processer_API_Guide.pdf

There is nothing in the API related to support Descriptors (apart of CCCD). Is there any way to create an HID device with this module or is impossible?

If this is not possible, is there any other module of BLE in TI to performs this actions and compatible with Educational MKII??

Thanks

Hi David,

Our devices certainly can be used to act as an HID device, however we don't have examples for it on most of our devices. Our Simplelink 2640r2 SDK BLE Example pack (I will link it below) contains an HID Keyboard example (called hid_emu_kbd). I don't think you could run this directly on the Msp432 + CC2650, but it would serve as a great baseline to give you an idea for how to perform HID and will likely answer most of your questions.
