CC2650 bricked after 6secs button combo reset

Other Parts Discussed in Thread: CC2650

Hi all,

I was using the CC2650 sensor via BLE for simple IoT demo purposes (so without dev skills needed)

It used to work well, but after some tests using the IoS app it connected only for a few seconds.

So I tried to use the 6sec button combo procedure to have it reset.

Since then I cannot see it using the App so I suspect it got bricked.

I've never flashed the firmware, only used to get sensor data.

Any advice on how to restore it without the need of the debugger connection?

Many Thanks!

can you try to replace the battery and see if it works?

Hi Christin, thanks for your help.

I tried with a new battery but still nothing..

Do you have any other procedure to suggest?

Many Thanks

Hi there,

It is possible that the device experienced an issue while applying the factory image.

Do you have a debugger available to re-flash a known good image to the device?

Hi Sean,
I don't have the debugger yet... is it the only option?

Thanks!

if replacing battery still can't recover, then the best(only) solution would be getting a XDS110 debugger and reprogram the ST.

Thanks Christin,

I finally got this: www.ti.com/.../CC-DEVPACK-DEBUG

Would you be so kind to point me to the right direction to for the correct re-flash procedure?

I need to re-flash the same stuff there was in the CC2650-STK, when I could connect and get sensor data with the IPad app.

Many Thanks!!

Hi all, re-flashed it now seems to work again.
Thanks for the help.
