Re: about BLE Rx test

I suppose you are performing RX sensitivity test.
> If RF equipment send a dbm above -86 (ex: -85 , -84 , -83 …..), the error message will disappear.
Assuming you are testing with BLE 2Mbps PHY, I think this behaviour is only to be expected given that the max. sensitivity is specified at -85 dBm at 2Mbps for nRF51824 (refer to the datasheet).

If this depends on the dBm setting it might be a bug actually. I’ll let Vinayak weigh in.
Sorry , correction.
We have a product using nRF51824 with Zephyr v1.13.0.
Our DUT connect with RF equipment.
Step1: DUT enter Rx mode with HCI command.
Step2: RF equipment send 1500 bytes with -86dbm.
Step3: DUT end Rx mode
After then , DUT will show “tx time out “ error message.
Could you give us some suggestions?
