BLE Between 2 NRF52DK

[NikTheNordicUser]

Hi there, i am trying to connect 2 nrf52DKs together and send data to each other. ONe of the NRF52DK works well an I can connect to the phone app and I can see the data but i would like to connect this to another nrf52dk i was trying to use the ble_central example ble_app_uart_c on the second board but when looking at the serial terminal if i send a certain character it doesn't send over BLE to the other board. 

For  clearer explanation i have this system:

Did you get this working with the unmodified examples before adapting for your sensor?

Are the boards connecting successfully ?

Do you mean it's not sent, or it's not received ?

yes as far as i know they are connecting as I am using 2 laptops and data is being sent between one another as expected. However, it is only sending the Accelerometer data which is set as default. And if i send a 'T' or 'G' from the client it doesn't send the respective data which means that the character is either not being sent or received however with a mobile phone app this works fine so it has to be from the client side. And i am entering the character T or G from the serial Terminal.

Hi 

Normally you have to type enter (some times ctrl + enter) in the terminal for the string to be sent. The newline character is used to decide when to send the incoming data over the NUS service. 

Have you tried this?

on the serial terminal it is shown as being sent ( the software has an echo function) but the character isn't seen to appear on the second pc

Hi 

What happens if you type in more than 20 characters?

The data will be buffered before sending, and the buffer should be sent out either if a newline character is received, or if more than 20 bytes are received. 

Best regards

Which software - the terminal, or the embedded  code?
