case about nRF52832 PAwR and nRF52840

[peter.min]

Hi

1. Can nRF52832 meet both 2 and 3 functional requirements?
2. nRF52832 of the smart lock is connected to the Bluetooth of the mobile phone to unlock.
3. The nRF52832 of the smart lock is connected to the nRF52840+nRF9160 gateway through PAwR to unlock.
4.nRF52832 smart lock and PAwR nRF52840 gateway in the case of 0dBm transmission power, how much communication distance can be achieved in practical applications?

Thank you for all your assistance.
Kind regards,

Hi Peter,

1. Can nRF52832 meet both 2 and 3 functional requirements?
2. nRF52832 of the smart lock is connected to the Bluetooth of the mobile phone to unlock.

Yes it can.

4.nRF52832 smart lock and PAwR nRF52840 gateway in the case of 0dBm transmission power, how much communication distance can be achieved in practical applications?

We performed some physical range tests between two nRF52840, and wrote about the result here:  Comparing range with Bluetooth Low Energy of the nRF21540 DK and the nRF52840 DK 
nRF52840 long range demo 

Please do note that the range was measured in close to ideal condition, with minimal electromagnetic noise. In a realistic usage condition, the number will be much different.

For nRF52840 to nRF52832, the result will be a little difference depends on the RX sensitivity differences at different modes of operation. Refer to the data in the nRF52840 Product Spec and the nRF52832 Product Spec.
