I am connecting multi peripherals to single central and i am using nrf53832 as central, how can i transfer the data to the central?

hi , i have tried its working fine , once we get connected to all peripherals , can we able to send the data to particular peripheral .

Hi,

Use this for central device: ble_app_lbs_nus_c

Use this for peripheral device : ble_app_lbs_nus

Yes, I tried same at my end and It successful.

nRf52840 DK as central and rest other 52 DK as peripheral.

When sending data from central through uart then all peripheral will receive it.

When sending data from peripheral then central deveice will receive it.

See the multilink demo steps on nordic infocenter for LED and button indications same is here for this demo.

Find attached zip file and extract it in example folder. use nRF52 sDK15.3.0.

hi archana Fugare have you tried , multi link merged with uart . can you share me or else what are things i should modify

Thanks in advance

Hi,

Use nRF52 15.3.0 sdk, under example folder paste nrf5-multilink-lbs-nus-example-master. Take three 52DK as peripheral and one 52DK as central(master).

Program it and send data through UART.

You will get the result. 🙂

Thanks & regards,

Archana

Not sure what the issue is. But I think it will be easier if you start with the Multilink example then add UART to it. Have a look at the UART central example and port over the parts that you need.

I have done whatever said by scott and I am not able to connect to multiple peripherals at a time. Even when I connected

to one peripheral also it is not able to send the data to peripheral or receive from it.

<info> app: Multilink example started.

<info> app: Start scanning for device name Nordic_Uart.

<info> app: Connection 0x0 established, starting DB discovery.

<info> app: Discovery complete.

<info> app: Connected to device with Nordic UART Service.

yughgh

<error> app: app_uart_put failed for index 0x0001.

<error> app: Fatal error

"I am getting above error in teraterm when trying to receive data from peripheral".

Can u help me how can i solve this problem?

Thanks in advance,

Kishor.

Hi,

Yes, it is possible to make a UART multilink central. You can use the multilink example and then add UART to it. I suggest you have a look at these two post, this and this.

Hope this helps.
