seems like you are trying to flash the s130 SD and application for nRF51? It will not run on the nRF52840. Anyways you can use the precompiled connectivity hex instead of generating the hex yourself: https://github.com/NordicSemiconductor/pc-ble-driver/tree/v4.1.1/hex/sd_api_v6 (connectivity_4.1.1_usb_with_s140_6.1.1.hex)

With the example hex file in this link http://www.nordicsemi.com/Software-and-Tools/Development-Tools/nRF-Command-Line-Tools/Download#infotabs on nrfconnect app it is as shown in the attatchment. It contains softdevice and application in the hex

But the generated hex file doesn't contain the application code it only had softdevice.

Am I missing any configuration.

I am facing the above error

For testing purpose I am using nrf52840 dongle

Here's the correct link: http://www.nordicsemi.com/Software-and-Tools/Development-Tools/nRF-Command-Line-Tools/Download#infotabs

Anyways, the command line tools require the nrfjprog DLL and we currently only supports this for Linux running on x86/64 architecture. However, the nrf52840 has a USB interface, and you can use UART over USB to communicate with the device. This way you remove the nrfjprog dependency.

I wrote an answer here to another question about running pc-ble-driver on a raspberry pi, https://devzone.nordicsemi.com/f/nordic-q-a/47329/connection-3b-armv8-and-nrf-52840-dongle/188449#188449 Don't know if that's helpful but you can have a look.

Hi,

We followed steps given in pc-ble-driver and able to build the pc-ble-driver, but for Connectivity HEX it is having dependency of nRF5x Command-Line Tools for Linux 64-bit.

We are not able to download it as it is showing 404 Page not Found error.

Is there any alternative way to download and install nRF5x Command-Line Tools for Linux 64-bit.

Thanks for the link.

Do you have any documentation on how to build pc-ble-driver on openwrt..??

Is it like we have to cross-compile and port it on openwrt running board..?? Will this work if we build it on ubuntu and port on to our host which runs on openwrt.

You can check out the serialization API: https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/lib_serialization.html?cp=5_1_3_42

The nRF52 will be running the BLE stack (softdevice) and your host MCU (in this case the MTK7628 as I understand) can communicate with the softdevice over UART (or other protocols).

The host software pc-ble-driver is written to be run on a PC and communicate over UART to the BLE stack. It is written in C and can be ported to your host MCU. It contains a couple of examples to get started. The examples in the SDK that normally runs on the nRF52 can also be ported to your host MCU (or used as a reference): https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/serialization_porting_guide.html?cp=5_1_3_42_5
