Error : "HCI_ProcessEvent" is undefined

Manan Gupta

Hello,

I am trying to run MasterSlaveSwitch application on my CC2540MINI-DK. For this I have downloaded the zip file from the following link :

But this is compatible for TI BLE Stack version 1.2 I think. So, I make the required changes mentioned at the following two locations:

After making all the changes mentioned here (except implementing the change to be made using example 1.2.1, as mentioned in the last link above, because I could not locate that example), I am facing a problem.

On Re-buliding all the files, I get the following error:

Error[Pe020]: identifier "HCI_ProcessEvent" is undefined C:\Texas Instruments\BLE-CC254x-1.4.0\Projects\ble\MasterSlaveSwitch\Source\OSAL_MasterSlaveSwitch.c 92

Can anyone suggest the solution to this?

Hello. I've ported the project to 1.4.1:

Hopefully this will fix your problem.

Hi Tim,

Yes the project is now working. The device is now able to switch between the roles. But when the device changes back from central to peripheral role, it doesn't start advertising again (although the red LED starts to blink, denoting peripheral role). Can you suggest a solution to this?

Thanks and regards,

Manan

I see this too. I'll try to get it fixed by early next week. A quick fix would be to do a software reset when you want to switch from central to peripheral. This should retain RAM but get you back to the beginning to reinitialize as a peripheral.

Hi,

It will very kind of you if you could please notify me as soon as that is fixed.

In the meanwhile, can you tell me how to do a software reset for switching it from central to peripheral?

Thanks and regards,

Hi,

I was able to reset the application using "SystemReset();". If there is any other method to do this, please do tell me.
Else, just inform me when you get this bug properly fixed and working.

Thanks a lot. Regards,
Manan

Hi,

I want to preserve the data which has been sent to my device acting as Central even after the switch occurs from Central to Peripheral mode. So, can I use SystemReset() for enabling the advertisement again? Is there any other alternate to this?

thanks and regards,
Manan

Yes, this should work: the device won't lose power so RAM should remain. The other solution is to fix this bug. However, I'm not sure when we will have time to do this.

Hello Tim,

All the variables are getting reset on calling "SystemReset()" and hence no data is being preserved. Can you suggest any other method to store data in some non-volatile location? Or is there any other method to reset the application so as to start advertising again by the device when it returns to peripheral mode?

Thanks and regards,

Manan

Manan,

We have had time to fix the bug within the example application. Please take a look at our updated wiki page with the newest patch uploaded.
