HOW DO I SET UP BLE WITH NRF XIAO BLE SENSE zephyr?

[massimoklk]

Hi!

I’m developing an application using nRF SDK 2.9.0 with the Xiao BLE Sense. I created a new project based on Zephyr’s UART peripheral example.

The application runs perfectly on the nRF52840 DK. It also builds successfully for the Xiao BLE Sense. However, when I deploy it to the Xiao BLE Sense, BLE does not work.

debugging it gets tuck to uart_callback_Set():

	err = uart_callback_set(uart, uart_cb, NULL);
	if (err) {
		k_free(rx);
		LOG_ERR("Cannot initialize UART callback");
		return err;
	}

I suspect I might be missing some configuration steps. Could this be related to the device tree (DTS) or some board-specific settings?

What additional steps should I take to get BLE working properly on the Xiao BLE Sense?

Thanks in advance!

Hello,

Can you share the prj.conf file of your application? Try including the configurations below inside prj.conf and see if this resolves the issue. I don't have this particular board you are using So I have some limitation testing this on my end.

CONFIG_UART_ASYNC_API=n 
CONFIG_SERIAL=n 
CONFIG_UART_CONSOLE=n 

Kind Regards,

okey, i will try it. However, the same project with the DK works well, meanwhile with the xiao blee seed does not. since the problem is the board, i do not think the problem is the prj.conf right?

additionally, i have disabled the uart and i have the application working on the xiao seeed board (BLE working). 
My goal is also to have the uart activated in the near future.

Thanks!
