Bluetooth 5 power consumption.

[nordicdev]

Hi,

1. I know this is a Bluetooth 5 spec question, but wanted to know the practical figures for current consumption when nrf52840 is used as both central and peripheral.

2. Also, will this current consumption be more in Bluetooth 4(nRF51822) than Bluetooth 5(nRF52840)?

3. I have read that Bluetooth 5 has increased range, yet lesser power consumption than Bluetooth 4. How is this possible to have a less power consumption yet increased data rate and increased range?

4. Also, even with Bluetooth 4 (nRF51822), we were able to get a range (in open air) of more than 100m (as opposed to 50m)? We did use a good antenna, so why cant we just use good antenna and use bluetooth 4 instead of bluetooth 5 if the intention is to just increase the range?

5. We have worked with nRF51822 for a while and find it to be awesome. However, we found nRF52840 has a comparitively long list of anomalies (in errata sheets). Do you have any timeline when the nRF52840 would be stabilized like nRF51822 with less number of anomolies?

I am having a tough time advocating for nRF52840 with the other team members, so please help...

Currently, there is no planned SDK updates for nRF51. See this answer for more details.

Thanks Jorgen for the reply. This answers my question.
