How to use nrf52840 mesh connect android phone ?

[woff]

I use SEGGER build mesh V4.1 project light_ctl and light_switch.

I flash light_switch_server_nrf52840_xxAA_s140_7.0.1.hex and light_lc_server_nrf52840_xxAA_s140_7.0.1.hex to nrf52840.

I download nrf mesh from google play to my Android phone.

I open bluetooth and lacation in my phone.

I create group, but I can not scan any device in my phone.

help me, thank you.

Hi.

Have you tried scanning for the device with another phone? Are you able to discover the device with another phone?

I step to step.

What's wrong with me?

Hi.

The problem seems to be that you are only flashing the application to the board. You will also need to flash the corresponding softdevice version.
If the softdevice isn't present, the phone will not be able to discover the device.

Using SEGGER Embedded Studio, the correct softdevice is added as an additional load file. (Project Options -> (Common configuration) -> Loader -> Additional Load file)
You can download the application and the softdevice in one operation by using Build -> Build and Run.

Br,
