NRF52840 dongle not scanable for mesh sdk 5.2.1 example, while working on nfr sdk 17.0 example ble_peripheral > app_bliinky.

Hi,
I am using 2 x NRF52840 Dongle, When I program one of my dongle with NRF SDK 17.0 example blue ble_peripheral>> App_blinky it works fine and gets connected to nrf connect app.

But as I change the program to mesh sdk 4.2 (example light switch) my nrf52840 dongle gets programmed but doesn't come in nrf connect app while if i program the 2nd one it works fine in both cases.

Can anyone guide me on it, its PC100059.

Hi,

mesh sdk 5.2.1

Is this a typo maybe? do you mean Mesh SDK 4.2? 

Hmm, strange that it only works for one of your dongles. If you use nRF Mesh app, can you see the dongle there?

So one of your dongle shows up in both nRF Mesh and nRF Connect, while the other one doesn't? This only happens when you run the light switch example?

Can you double-check that the exact same firmware is run on both dongles? 

Also, both dongles are the same? Haven't done any modifications?

Both are PCA10059, having same firmware, both shows up when I run SDK 17.0 example ble_app_blinky, But when I upload the the mesh example on both, only one work other doesn't. Purchased them recently from mouser.

Can you try one of the other mesh examples on both dongles? Like the beaconing example? Can you find both dongle?
