I see,

Since SoftDevice S140 version 6.1.1 is able to receive at 125 kbps (S=8) and 500 kbps (S=2). But it can only transmit at 125 kbps (S=8). So you cannot set S=2 for a connection explicitly, but the connection can recieve S2 coded data.

Radhima,

The Phy update procedure MSC can be found here.

Implement BLE_GAP_EVT_PHY_UPDATE and BLE_GAP_EVT_PHY_UPDATE_REQUEST.

There is a useful blog that I wrote when long range feature was out in software and you can see find the project I used in the end of the blog. You mostly can check how different phy are set there.

Try the peripheral example here: devzone.nordicsemi.com/.../8713.Long_5F00_range_5F00_15.2.zip

Be aware that only very few phones supports long range at all. BLE 5 normally means 2 Mbps.

https://github.com/opendroneid/receiver-android/blob/master/supported-smartphones.md

Some even have to connect at 1 Mbps and change to LR when the link is up

The example you link to should do what you want, no?

ok thankyou for information.

so can u assist in example where long range is supported by nrf52840/33

RE: long range

ketiljo — Fri, 25 Jun 2021 07:05:50 GMT

You can't as the nRF52832 doesn't support long range. Only the nRF52811, 820, 833 and 840 supports that. See https://infocenter.nordicsemi.com/topic/struct_nrf52/struct/nrf52.html
