CC2541 Indication values are not viewing on Btool and iphone's LiteBlue App

Hello,

I am using Indication other than Notification in the Thermometer sample application's Temperature measurement characteristics .The indicated Values are not viewing on Btool and iphone's app.What are the points to be taken care to get the indicated values on the device??

I also followed application Sample Guide for the same.

I also changed : noti.pValue = (uint8 *)GATT_bm_alloc( connHandle, ATT_HANDLE_VALUE_NOTI, GATT_MAX_MTU, &len ); to

noti.pValue = (uint8 *)GATT_bm_alloc( connHandle, ATT_HANDLE_VALUE_IND, GATT_MAX_MTU, &len ); in the gattServApp_SendNotiInd().

Thanking

Hello. Have you configured the temperature characteristic for indication by writing a 0x02 to the client characteristic configuration attribute?

FYI there is a similar thread here: e2e.ti.com/.../467585

Hello Tim,

Thanks Tim for the reply .
I configured the temperature characteristic for indication by writing a 0x02 to the client characteristic configuration attribute then it will indicate value once and many times it gets disconnected.

It is also giving indicated values when other than 0x02 is written.

In notification we get notified values continuously as we click on Listen for notification Button in LiteBlue App.Similarly indicated values gives value once.Is it because periodically calling of notification event?

Please let me know the issue.

Thanking,

vikas

Are you replying to the indication with an ATT confirmation?

When you receive an indication, you must respond with an ATT confirmation. This is standard procedure as defined in the spec. For example, see section 4.11.1 of volume 3 of the 4.0 spec.
