Hi James,

I attached here the ble_app_hrs example on the S120 side and S110 side where Indication is used to update the HRS value instead of notification. I have no problem getting the indication and confirm it.

Could you please try and let me know if there is any issue. The examples are from SDK v6.1, S110 v7.1 and S120 v1.0

ble_app_hrs - Indication.zip

ble_app_hrs_c - Indication.zip

Hi Pål ,Thank you again for answering,I have noticed the confirmation which the s120 side have to send when receiving the indication.I have done the confirm in my s120,so i think it may be not the reason of the problem. Is there some other place the i need to notice and set?

In the s120 side you would have to send a confirmation with the sd_ble_gattc_hv_confirm function when you receive the indication. That is when you would receive the BLE_GATTS_EVT_HVC event on the s110 side.

hi Pål , thank u for your reply,it was my fault that I pasted the wrong code.In my project i have repalced the notification with indication.,so there must be another reason causing this problem .Did i have to make any other change to implement the indication?

Hi james,

Looking at the code, it looks like you forgot to change the hvx_params.type to BLE_GATT_HVX_INDICATION (at least in the code that you pasted)
