Hello.
Here is my some information.
I tried write hex file this.
- nRF_SDK/examples/dfu/secure_dfu_test_images/ble/nrf52832/sd_s132_bootloader_buttonless_with_setting_page_dfu_secure_ble_debug_with_bonds.hex
But application shown this message.
I was never seen this message before, when I use 'nrf connect for desktop 3.6.1' version.
I can not dowgrade, 'nrf connect for desktop' application do forced installed lastest version.
What can I do something?
