Glad to hear you were able to figure this out on your own!

Best of luck and regards,

I found the problem had not changed the value of:

#define NRF_BLE_SCAN_BUFFER 31

to:

#define NRF_BLE_SCAN_BUFFER 255

i found it in : https://devzone.nordicsemi.com/f/nordic-q-a/50639/nrf52840-dk-change-scanning-phy-to-coded-phy

thanks!

Thanks Simonr,

i read the example, i have a similar code, when i say "i can see long range beacons, but only one time" i´m trying to clarify:

1._ i have long range beacons working

2._i have nrf52840 dk working with a long range advertising scanner on it.

But it stops when a first beacon apeared and the if a iwant to see another beacon or advertising i need to switch off and on the nrf52840 dk.

This behaviour only shows with BLE_GAP_PHY_CODED if i change it for BLE_GAP_PHY_AUTO, i can scan beacons once and once again.

I dont understand why my code only scan 1 device with the BLE_GAP_PHY_CODED enabled,

I hope I have explained myself better this time.Thanks!

Can you specify what you mean about this? Did you see them at one point, but then changed something in your project and now you're not able to see these beacons anymore?

Please check out this modified example project, which should include everything necessary for scanning for long range devices.
