  Please understand that it is English using a machine.

Hello. I try to create a module using nrf52810 and nrf52840. We are testing "secure_uart_pca10040_s112", an example included in sdk.

You can upload to nRF 54 open board and connect with test, iPhone  x or can not connect with iPhone x at s132 upload.

I want to know the reason, I would like to create a module like hc06 that can be used easily and easily. Using my example, I would like to change some parts and know if some examples should be corrected. I want you to help. Thank you.

Hi,

Is it the case that you are using the secure_uart_pca10040_s112 project and want to do DFU from an iPhone? If so that won't work, as the secure_uart_pca10040_s112 use UART transport layer (wired UART), which is probably not what you want. You need to pick a BLE bootloader project, for instance <SDK>\examples\dfu\secure_bootloader\pca10056_ble for the nRF52840. I also recommend you read Getting started with Nordic's Secure DFU bootloader, a step by step guide.
