Hi,

we are trying to take Korea certification but the lab asks us this:

In one hopping channel the dwell time must be within 0.4 second at BT LE mode.

But your command cant on-off and continiusly output signal so Korea Lab cant measurement Dwell Time at BT LE mode.

But EDR and BDR is can measurement Dwell Time

We are not sure on how set our EUT in this mode.

Any cosndierations about this?

Thanks

Hi,

When testing the device for certification are you using HCITester App with UART communication to the device, or a Linux based system?

In general I would recommend you refer to our WL18xx Bluetopia PM Bluetooth RF Testing app note (Lit# SWRA750). You can also refer to the responses from our BLE expert Rogelio in this E2E thread: https://e2e.ti.com/support/wireless-connectivity/wi-fi-group/wifi/f/wi-fi-forum/1275784/wl1837mod-wl1837mod.

Hi,

I used Linux based system. We have already taken a look on the RF Testin App WL18xx Bluetopia PM Bluetooth RF Testing app note (Lit# SWRA750) but the paragraph relating to BLE TX packet transmission is void (5.1.1.2 Packet TX RX).

The lab is able to perform all the test with the commands taht we provided them except for the BLE .

Hi Laura,

Unfortunately there is not a way to configure dwell time on BLE. You can refer to past E2E threads discussing this and the Korean testing:
