If I used a nrf52840 bluetooth5 as a server, but customers have iPhones with Bluetooth 4.x on, will the range still be 2x or 4x, as stated by BT SIG?
Did Nordic test the range with Bluetooth 4.x phone?
I do not have a nrf52840 board yet.
I currently have 132 10040 nrf5283 device on my board, but the distance / range is not enough for the application. So I thought perhaps BLE5 will do the trick?
Any advise appreciated
