What will the range be with a ble 5 server, but iphone with Bluetooth 4

[Renix]

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

Hi,

I guess no phone today supports BT 5.x "Long Range" data rates (500/125kbps), certainly not iPhones currently in the field. To be honest this BT 5 feature doesn't look like anything desperately needed on the phones (= you want to create local connection with your gadgets, car etc., certainly not to communicate on hundreds or thousands of meters) so it wouldn't be surprising if there would be no phones/tablets at all equipped with this feature in the future (remember that many features in BT SIG specifications are optional so you don't need to support everything to have sticker "compliant with BT5"). If you have issues with the range I'm afraid BT5 won't help you (nor today neither any time soon), only better antenna tuning, chip sensitivity or totally changing architecture (e.g. is BLE really right solution?).

Well, Samsung Galaxy S8 will be the first phone that support Bluetooth 5.0. According to several tech-magazines and websites it will support the Long Range feature, but I haven't seen any thing official from Samsung on this yet.
