Part Number: MSP432P401R
Other Parts Discussed in Thread: CC2650

I have the MSP432P401R Red with a CC2650MA booster pack.

I'm using cloud tools.

Yesterday I ran ProjectZero and it was detected using the LightBlue App on my iPhone. I was a happy camper.

I did exactly the same thing today and ProjectZero is no longer seen by LightBlue.

I rebooted everything several times, rebuilt the program, deleted LightBlue and reinstalled it. Rebooted my iPhone, etc, etc and the ProjectZero program simply no longer seems to be working.

I think the MSP432 and CC2650 must be OK because everything builds and loads OK, I'm getting output to PuTTY.

Any idea why it would work one day and not the next, all in the same environment, same conditions?

Hello,

<<< I think the MSP432 and CC2650 must be OK because everything builds and loads OK, I'm getting output to PuTTY.

Based on your answer and my past experience I would look for a solution on an iPhone site.

Tried everything suggested to clear the GATT cache on iPhone but still nothing.

Hey Adam,

Could you give a screenshot of what the PuTTY terminal looks like? My suspicion is that you might have accidentily pressed the firmware update button on the LaunchPad. By default a firmware image of the CC2640R2 (newer gen than the CC2650) is programmed to the flash of the MSP432. If you press the firmware update button it will update the CC2650 with the CC2640R2 firmware and quit communicating.

Try to do an external update of the CC2650 firmware using this method:

... and see if it fixes the problem. I doubt it is an iPhone issue if you reboot your iPhone and it still doesn't work (there is an issue with caching in iOS, however this goes away if you reboot the phone).
