Hi, I am working on IoT device and intersting to that field I am wondering can I know your name for following your work or your email address for some questions?

If you are really interested into power consumption profiling then you need to know all radio activity (e.g. including empty LL PDUs exchanged during every connection event even if there is no L2CAP/ATT/GATT/APP activity on top of it). Then sniffer is your way to go!

Does BLE_EVT_TX_COMPLETE include host initialized reading either? I am doing a power statistics feature, just like android phone does, not just for power estimation in lab. So I need a way to count all tx/rx bytes through BLE, then I can get how much current consumed by RF.

Hi,

You will get an event called BLE_EVT_TX_COMPLETE every time a packet you have queued for transmission using one of the GATTC/GATTS/L2CAP APIs has been successfully transmitted to the peer, with a count field telling you the number of packets sent. However, that "count" field only counts user packets, and not system packets, meaning that it won't correspond to the actual number of packets that have been sent over the RF link.

So if you want to see all the RF activity you will have to do a sniffer trace as endnode suggested.

Just use sniffer and count it experimentally.
