nRF54L15 Channel Sounding - Channel Range

[Jimba]

Dear Nordic Team,

Does the nRF54L15's channel sounding function use the channel range of 79 channels (72 channels excluding the advertising channel) stated in the Bluetooth SIG specification?

Part H Channel Sounding

Hi

1. I believe the 40 channels you refer to are 2402MHz-2480MHz with 2MHz channel spacing, Channel sounding uses the same range of frequencies, but with only 1MHz spacing so I think this should still be within the specificaiton. I assume the Japanese Radio Law has its own section for Bluetooth Channel Sounding, but I don't know that for sure. Please contact a certification house or similar as they would know for sure.

2. My assumption would be that this is included in the allowed range, but I would check with someone intimately familiar with the Japanese Radio Law whether that's the case.

Best regards,

Simon
