nRF52832 send a custom message to Raspberry Pi via BLE without UART.

Hi

I am using nRF52832 DK with SES as IDE, on Ubuntu 16.04 machine. I want to send a custom message, let's say "hello" via BLE to Raspberry Pi. I am using some encryption algorithms to encrypt this message. I want to receive this message and decrypt on Raspberry Pi using the inbuilt Bluetooth module. I have looked at ble_app_uart which sends the data received via UART. I have noticed that UART is very slow and to improve the speed, I want to transmit the message from DK to Raspberry Pi using Bluetooth. In this case, I do not get any data from UART. Is there any way to do this? And on the Raspberry Pi, I want to do some operation on the data. Any thoughts on how to go about this?

Thanks

Hi,

I'm not sure what you mean by slow. If you're using the ble_app_uart peripheral example then you need to setup a central on the Raspberry Pi that is similar to the ble_app_uart central example. This has been discussed numerous times in the forum, see for instance this post.

I used Python code to send data through Serial Port. The sending portion of code is in while(true) loop. I had to put a delay of 2 seconds between 2 successive sends. This is what I meant by slow. So, I want to avoid using UART. I just want to use Bluetooth and send data.
