How does a nrf5340 communicate with several nrf5340s in both directions using BLE and Visual Studio?

Hello,

You have to uncomment three configuration

CONFIG_BT_LL_SOFTDEVICE=n

CONFIG_BT_LL_SW_SPLIT=y

CONFIG_BT_CTLR =y

as I said in my previous reply.

Hi Kazi,

Thank you very much for your reply.

Following your comments, I have tried to build the project. But it still did not work. You can see the attached errors. here, I would like to control transmit power of the radio, therefore I think the following configurations should be used:

# Transmit power

CONFIG_BT_LL_SOFTDEVICE=n

CONFIG_BT_LL_SW_SPLIT=y

CONFIG_BT_CTLR_ADVANCED_FEATURES=y

CONFIG_BT_CTLR=y

CONFIG_BT_CTLR_CONN_RSSI=y

CONFIG_BT_CTLR_TX_PWR_DYNAMIC_CONTROL=y

Can take a look at this again?

BR,

Lan

Hello,

yes, I have taken a look. Along with uncommenting these following two configurations, I have uncommented CONFIG_BT_CTLR. Then I was able to build and flash.

CONFIG_BT_LL_SOFTDEVICE=n

CONFIG_BT_LL_SW_SPLIT=y

CONFIG_BT_CTLR should not be set in the application's prj.conf for nRf5340 application as it is for the network core; hci_rpmsmg image, where Bluetooth LE controller is. In application core, we have Bluetooth LE host only.

You can try this. It should work

Thanks.

Hi,

Did you take a look at the prj.conf file?

I commented on all configurations from line 30 to line 40. This is why you can build, and then flash it well.

Hello Lan,

I have built and flashed the sample on nRF5340. It was flashed successfully.

''I tried with your suggestion, but it does not work. '' Could you please tell details about the error and what did not work?

Thanks.

Hi,

I will look at this and will give you answer later.

Thanks.

Hi Kazi,

I tried with your suggestion, but it does not work.

The attachment is my project. If it is possible, would you look at the prj. conf file and project?

Hello Lan,

Can you try to delete these following two configurations?

CONFIG_BT_LL_SOFTDEVICE=n

CONFIG_BT_LL_SW_SPLIT=y

Hi Kazi,

Many thanks for your answer.

I tried to change the transmit power when using the Peripheral_UART example. First, I used several functions from the hci_pwr_ctrl example such as

static void read_conn_rssi(uint16_t handle, int8_t *rssi),

static void set_tx_power(uint8_t handle_type, uint16_t handle, int8_t tx_pwr_lvl),

static void get_tx_power(uint8_t handle_type, uint16_t handle, int8_t *tx_pwr_lvl),

and I called one function as

set_tx_power(BT_HCI_VS_LL_HANDLE_TYPE_CONN, 0, -40);

The project is built well.

Then, I add more configurations as: (https://devzone.nordicsemi.com/f/nordic-q-a/72611/how-to-config-nrf5340-tx-power) and (https://devzone.nordicsemi.com/f/nordic-q-a/91709/how-to-set-transmit-power-for-ble-in-nrf-connect-sdk)

CONFIG_BT_LL_SOFTDEVICE=n

CONFIG_BT_LL_SW_SPLIT=y

CONFIG_BT_CTLR_ADVANCED_FEATURES=y

CONFIG_BT_CTLR=y

CONFIG_BT_CTLR_CONN_RSSI=y

CONFIG_BT_CTLR_TX_PWR_DYNAMIC_CONTROL=y

Then I rebuild the project again. However, the project can not be built with several warnings as follows:

warning: Experimental symbol BT_LL_SW_SPLIT is enabled.

I have tried to change various configurations but it did not work. Would you please suggest me a way to fix this?

Thank you very much.

Hello Lan,

We have peripheral_uart and central_uart sample that you can look at as a start: Bluetooth: Peripheral UART — nRF Connect SDK 2.1.99 documentation (nordicsemi.com), Bluetooth: Central UART — nRF Connect SDK 2.1.99 documentation (nordicsemi.com).

Thanks.
