Hi.

[quote user="deadpoolcode"]flash works, but when I am committing FOTA, FOTA failes.[/quote]

But how do you create the FOTA packet? What command did you use? Have you followed the test procedure here for example?

Best regards,

Andreas

Hello

I am using the "secure_bootloader\pca10040_ble" + software based on "ble_app_buttonless_dfu" + "s132_nrf52_6.1.1_softdevice.hex"

script to flash software:

#erase chip
nrfjprog --family NRF52 --recover
#program softdevice
nrfjprog --family NRF52 --program .\firmware-img\s132_nrf52_6.1.1_softdevice.hex --chiperase
#program bootloader
nrfjprog --family NRF52 --program ..\nRF5_SDK_15.2.0_9412b96\examples\dfu\secure_bootloader\pca10040_ble\ses\Output\Release\Exe\secure_bootloader_ble_s132_pca10040.hex
#program software
nrfjprog --family NRF52 --program .\Project-nRF52832\Output\Debug\Exe\BLE-nRF52832.hex
#reset chip
nrfjprog.exe --family NRF52 --reset

flash works, but when I am committing FOTA, FOTA failes.

however, if I reprogram device application only ("ble_app_buttonless_dfu") using segger, power device on\off, from that point on flashing using FOTA works

what am I missing?

Hi.

Which command did you use in the command line? Can you share it with me?

What does your application contain?

Please explain more in detail.

Best regards,

Andreas

I created the package using command line, it contains application generated by segger. the FOTA works perfectly if I flash the application using segger, but if I flash the application using command line, all works but FOTA fails

How did you create your firmware packet? What does it contain?
