ATT_MTU throughput example: data received by responder?

Question

Hello, I'm running the nRF5 SDK's ATT_MTU throughput example and I want to check that the data sent by the 'tester' (nRF52832 in my case) is effectively received by the 'responder' (nRF52840 in my case). 
 I can check the data sent by the tester but don't see where the data received by the responder can be found in the code. 
 Anyone that can help me, or tell what I need to do to find it? Thank you very much!

Hi Luc 
 Thanks for the clarification. 
 Apparently the data pointer is not forwarded to the application event handler. I wasn't aware of this myself to be honest, but since this example is intended to measure the transfer speed, and doesn't really care about the data content, I expect that to be the reason. 
 If you want to change this behavior you need to modify the amtc.c/h implementation and add another field to the amtc event structure. 
 In the on_hvx(..) function in amtc.c you can access the notification data through the p_ble_evt->evt.gattc_evt.params.hvx.data pointer, and if you extend the amtc event you can forward this pointer to the application so that the data can be processed. 
 Best regards Torbjørn
