RE: NRF5340 FOTA, system reset after pairing

Hi Simon,

Thanks for outlining those test steps. I haven't yet gotten a chance to do that and it may be a few days before I have time to do so. I just thought I would ask about Android on the off chance you were able to respond.

Unfortunately I can't upgrade my phone to Android 9 but there may be another device in the office that I can use for testing.

I'll let you know how my testing goes.

Sincerely,

Doug Young

Have you tested the steps I mentioned? Is it still failing

I'm running Android-version 9. Are you able to update to that version?

Best regards,

Simon

Hi Simon,

What version of Android are you running on the Galaxy S8+?

Thank you,

Doug Young

I was able to perform FOTA (Bluetooth) using an nRF5340 PDK v0.7.0 and the smp_svr sample (NCS v1.4.0), with the nRF Connect Device Manager app on a Galaxy S8+

I did the following:

cd into C:\Users\Simon\ncs\v1.4.0\zephyr\samples\subsys\mgmt\mcumgr\smp_svr
Connect the nRF5340 PDK to the computer and turn it on
Run west build -b nrf5340pdk_nrf5340_cpuapp -- -DOVERLAY_CONFIG=overlay-bt.conf && cd build && west flash
Add CONFIG_BOOTLOADER_MCUBOOT=y to <..>/zephyr/samples/hello_world/prj.conf
cd into zephyr/samples/hello_world
Run west build -b nrf5340pdk_nrf5340_cpuapp -d build_dfu
Transfer <..>/zephyr/samples/hello_world/build_dfu/zephyr/app_update.bin to the phone
Install and open the nRF Connect Device Manager app on the phone, then connect to the nRF5340 which should be advertising with the name "Zephyr"
Perform a Firmware Upgrade using the app_update.bin file
You should see the following log from a serial terminal (e.g. Termite) from the nRF5340 if the DFU update was successful:
