BLE Communication between two nrf5340

Hi, 

You can start from 

• Bluetooth: Central UART
• Bluetooth: Peripheral UART

Hi Amanda

thank you very much for the tips.

While testing those samples, I can't get any output, that the Kits are connected. I only get a message "Starting Bluetooth Central UART example" in NRF TERMINAL, but nothing else. On the Kit with the Peripheral sample on it indicates the LED 2 that the Kit is connected, but in NRF TERMINAL is also only the "Starting Nordic UART service example" message. I also connected PuTTy to the Central, but I don!'t get any message here. I did not change anything in the Samples so far.

Could you please give me an advice, what should I do?

Regards, Jirik

Hi, 

In the UART samples, the UART console is used to send and read data over the NUS service. Debug messages are not displayed in this UART console. Instead, they are printed by the RTT logger. If you want to view the debug messages, follow the procedure in Connecting using RTT. Once you connect via RTT, you can the event logs.

Hi Amanda

Thank you very much for tips, I think I understood the connecting and the communication between the Central and Peripheral. Now I have problems with getting the data from the temperature sensors to the UART sending buffer. I get the temperature data with SPI interface as uint32_t.

Would you have some advice for me?

Hi, 

Take a look at the ble_write_thread function and this tutorial.
