Hello Everyone!

Hello Everyone!
I am going to design an edge device with nRF52840 for BLE protocol with smoke detector sensor.
In this case, I am going to get range about 100 ft.
so I would like to know if nRF52840 is suitable to my case.
furthermore, if someone has schematics reference design with nRF52840, please let me know about that.

May i know, which development board of the nRF52840 are you using for the project, or will you designing a custom PCB for the nRF52840

The video, should be able to give you an estimate to what you would get as the range on a nRF52840DK
(https://www.youtube.com/watch?v=w4PbxVwg83M)
Range in wireless changes based on a lot of param
1. if you want unidirectional, bidirectional comms
2. Environment(For Ex: Outdoor or Indoor)
3. Packet load
to name a few..

Nordic Semiconductor – Bluetooth 5 Long Range Test with nRF52840

The nRF52840 SoC is high-end multi-protocol SoC supporting Bluetooth 5/ANT/ 802.15.4/ 2.4GHz proprietary. The video focuses on the improved range achieved by the higher output power combined with the new Bluetooth 5 Long Range mode. In the video we are using the nRF52840 SoC mounted on the nRF52840 Preview DK (now replaced by the nRF52840 DK).

You probably already saw this, @here, but there's a reference design schematic for the 52840 here: https://discord.com/channels/1130679493799977062/1230604933699600495/1262443909980622942
