How to verify the 4Mbps transmission mode of the nRF54L15 series?

[Cytheria]

I noticed that the product information of the nRF54L15 series kit supports 4Mbps, but I'm unsure how to verify it. Are there any relevant examples available? I have currently tried the radio_test example, but this example doesn't show the actual data rate.

Hi,

4 Mbit phy is for proprietary protocols only, not BLE (which goes up to 2 Mbit.)

With the radio test sample in nRF Connect SDK v3.0.0, when building for the nRF54L15 DK, you should have the additional options to select data_rate of nrf_4Mbit_BT04 and/or nrf_4MbitBT06.

You can also test it with Enhanced Shockburst (ESB) using the ESB samples, by changing the configuration structure in main.c used for esb_init() from

config.bitrate = ESB_BITRATE_2MBPS

to

config.bitrate = ESB_BITRATE_4MBPS
