Sending data OVER ble uart TX characteristics to an access point

[Manjunath K S]

Onl

I have 40 kb of data  i need to send, and what i thought was using notification by creating a timer, which will be started as soon as device gets connected, in the timeout handler i will convert every data to string using sprintf  7 send in that for loop, which will be written inside timeout handler, but i am not able to receive all the data y.

or what should i do to achieve this in Uart ble example project , please help me ASAP.

There's no need to use printf - NUS can handle raw binary data.

Relying on blind timers is never a good thing - uses the status return from NUS to know when it is ready to accept more data

Which status i need to check , can u explain me in detail.

Take a look at how the SDK example does it ...

[Manjunath K S]

can u please help me with that understanding not able to follow how to get to know the status u are talking about.

Again, look at the SDK examples.

They illustrate how to use the NUS API function calls.
