The power estimation tool on https://devzone.nordicsemi.com/power/ maxes out at a minimum interval of 7.5ms and a maximum payload of 27 bytes, with 824mA average current. As discussedon the blog post that was published with the tool, this is nowhere near the bandwidth of BLE 4.2 or BLE 5, but the tool has not been updated yet to reflect higher throughput.

Can someone who has tested this tell me what current or power consumption you see closer to the maximum bandwidth of BLE 4.2 or BLE 5?

Hi, I'm working on updating the online power profiler now, and it should be out soon with BLE 5 support. You can also use the tool as it is now to calculate for higher bandwidths if you do some calculations on your own. For example if you want to enable data length extension in your application you can extend the radio lengths with 1 us for each bit (1Mbps). Then you have additional_length*radio_average_current = additional_event_charge. And additional_event_charge / ble_interval = additional_average_current.
