about BLE Rx test

Tommy Lin (林志聰) <Tommy.Lin@...>
Hi , 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.
PS: 1. If RF equipment send a dbm below -86 , 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, Tommy

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

Hi,
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).

Hi Stephanos, Thanks for your response. I have following question: 1. By Default , What data rate (1M or 2M bps) are set in zephyr code ? if it is 2Mbps , How can I set it to 1Mbps?
PS: Our RF equipment only support in 1Mbps.
Thanks Tommy

Hi Tommy,
To test 2M Phy please use LE Receiver Test Command [v2] with OCF 0x0033 instead of the v1 command you are using.

Hi zephyr,
