Re: about BLE Rx test

Adding Vinayak.


If this depends on the dBm setting it might be a bug actually. I’ll let Vinayak weigh in.

Hi ,

Sorry , correction.


We have a product using nRF51824 with Zephyr v1.13.0.

Our DUT connect with RF equipment.


[Test sequence]

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.




  1. If RF equipment send a dbm above -86 (ex: -85 , -84 , -83 …..), the error message will disappear.
  2. We use Zephyr v1.13.0 and v1.14.0 , and the result is the same.


Could you give us some suggestions?


Thank You,
