High PER at 2Mbps

[Michael]

Hi,

Scenario:

Two nRF52832DK boards on a table, approx 20 cm from each other, +4dBm output power.

Payload length is ~60bytes.

Running at 1Mbps gives me less than 0.1% PER, running at 2Mbps gives about 25% PER. (everything else kept identical)

Is this expected, or is there something at play here?

[Michael]

Nope, no WiFi or anything else... Spectrum is almost empty here... the same difference regardless of what channel I'm using....

And at that distance, if anything would affect the reception to a large extent it would probably be receiver saturation in that case.... But it that case, why such a difference between 1Mbps and 2Mbps...

[Michael]

Expected throughput is irrelevant in this topic... This has simply nothing to do with throughput at all actually...

I donated know what's confusing with the question... And where did BLE overhead come in to the question?

Let me clarify the question again so that we please could leave throughput and BLE overhead out of it since it's irrelevant... I'm not even using the soft device... And throughput and packet error rate is two completely different things, even though PER can influence the throughput...
