Hi Amanda,

Thank you for your help.

I was able to solve my issue and now I can flash using nRF Connected Device Manager.

Here are the major changes I made when it started working:

Changed from BT_LE_ADV_OPT_USE_IDENTITY to BT_LE_ADV_OPT_CONNECTABLE

Decreased my advertising interval from 10s to 500ms

Increased my while(1) loop k_sleep time from 1ms to 100ms

Thank again,

Liz

What application are you running on the custom board?

Could you test with the Nordic Academy example on your custom board?

If you have an empty while loop without any k_sleep() or similar it will consume all available CPU resources, blocking any lower priority threads. Check out this post.

Hello! I tried the Nordic Academy example using the nrf52dk and it worked. I tried to replicate the steps for my custom board and unfortunately it still does not work.

I have been using the nRF Connected Device Manager app.

Here are the states I get:

REQUESTING MCUMGR PARAMETERS

REQUESTING BOOTLOADER INFO

VALIDATING

Sending the request timed out.

Hi,

[quote user=""]I am trying to use the DFU pack to flash my device using the phone app nRF Toolbox or nRF DFU (I am trying both)[/quote]

Please use the nRF Connect Device Manager app for mobile (Android and iOS). Also, check this Nordic Academy course: FOTA over Bluetooth Low Energy.
