Will sending large data to mobile phone block other task?

[kian79]

Hi all,

I am working on a project which receives data from UART (15 bytes at every 40ms interval). I want to store 1 minute of data on the NRF52832 RAM before sending it to a mobile phone.

This can be quite a lot of data to transfer and I am planning to use the ble_app_uart example. I believe it will take quite some time to transfer this data to the mobile phone. But at the same time while data is sent to the mobile phone, I want to continue and receive data via UART at every 40ms.

So my question is, while there is an active connection and there is data transfer via BLE to a mobile phone, can the UART interrupt the connection?

Otherwise, is there another better strategy for this? Ultimately, I have 15 bytes of data coming from UART every 40ms, and I want to send this data to a mobile phone. I hope to fill up a large buffer first then send out the data.

Thanks in advance.

Uart cannot interrupt the ble communication. But you should have plenty of time to receive the 15 bytes inbetween connection events. See interrupt model and processor availability.
