nRF52833 LR(Long range testing) Set UP for (Coded PHY)

[Swapnil Karkare]

Hi,

We want test nRF52833 support on long range. I referred https://github.com/NordicPlayground/nRF52-ble-long-range-demo.

So as first step we use nRF52840 dongle for advertising and able to advertise. It is verified on Onpluse 6 device as shown in below.

Now for scanning we use nRF52840 DK as mentioned in above link. 

We are facing issue in scanning(central mode). We are not getting any advertise packet on DK. But when i used Oneplus device to advertise as long range we started getting scan responses but with MAC address.

Could you please guide on above?

Okay, sorry about the misunderstanding. 

In order to scan using Coded PHY, you also need to set the NRF_BLE_SCAN_BUFFER to BLE_GAP_SCAN_BUFFER_EXTENDED_MIN (which is 255). What kind of failures are you seeing when you start scanning? 

Please check out this modified ble_app_uart central example that has been modified to scan for Coded PHY advertisements if you need a template.

Hi Simon,

Thanks for guidance. I am able to implement both advertising on nRF52840 and scanning on nRF52833.

There one more query regarding bit rate transmission. We want to test it on both (S=8) 125Kbps and (s=2) 500Kbps setting.

How can we set this setting?

Hi again

Glad to hear that you're able to advertise/scan as intended now. Our SoftDevice only supports the (S=8) PHY as of yet, so there is no option to test with the (S=2) 500kbps setting I'm afraid.

Best regards,

Simon
