Single central multiple peripheral is not working

[shikgom2]

I want to connect and get data multiple peripheral to a single central device.

I used this example https://github.com/NordicPlayground/nrf52-ble-app-uart-c-multilink

I debugged this project, I saw this error in this picture.

If I turn on a single peripheral device,  I saw this warning like this picture, But it can't get peripheral's tx data.

But I connect my phone, I can get peripheral's tx data.

How can I solve this error??

Hi Carly, 

Did you modify the example? If so, what did you modify?

For the first error, please erase the kit before downloading the image. 

For the second figure, you have to send data to one of the boards using the serial port. Observe that the data is displayed on the UART on the other board. Please use the terminal tool like putty to connect the central and the peripheral. You will get peripheral's tx data on the UART.

Thanks for your answer.

I didn't modify the example code, I erase j-link and build again, But the same error occurred.

And, I use the terminal tool, There is no data coming from COM PORT.

When I added nrf_delay_ms() during BLE connection time, But It didn't work very well...

Maybe I solve NRF_SOLVE_BUSY this error first.

how Can I solve this error?

Hi Carly, 

Could you erase the board (1D:EE:13:3A:BB:DF) and load UART/Serial Port Emulation over BLE image again?

Please let me know how it works. Thanks.
