nRF52840 Coded Phy Range Problem

[Aamir]

Hi,

I am using nRF52840 Enineering C chip on a custom board using SDK v15.3.0 with SoftDevice v6.1.1

I have modified the Blinky Central code and the Blinky Peripheral code to work in Long Range mode using Coded Phy.

The receiver on the Central is ON 100% of the time, and the peripheral is advertising at 100 ms interval.

The Range results I got while changing the tx power of peripheral is as follows:

Coded Phy 8 dbm tx power - 250 meters

Coded phy 0 dbm tx power - 170 meters.

1MBps Phy 0 dbm tx power - ~100 meters

1MBps Phy 8 dbm tx power - 150 meters

This is way less than expected, how can the range be increased further ?

Very well, then your application code is off the board, which means the problem is either with your test environment or the custom board. You could try contacting HolyIoT to see if they've done any long-range tests with their module to see if they've gotten any better results, or try conducting your test in a more suitable environment for long-range communication.

Best regards,

Simon

Thanks for your reply,

Yes we are in talks with HolyIOT and we'll also be doing the tests again in a more suitable environment. we're also in talks for the new DKs. so, we'll have a reference at all times.
