UART receive before handling

[DragonAnger]

Hi,

I'm using nrf51822 and ble_app_uart(SDK 12.3.0).

I'm sending data from my android phone.

My question is that what happen if send data before previous data is not handled

in nus_data_handler() in main.c.

I do some work in nus_data_handler(). So sometimes it seems that data received

before previous data is not handled.

Should I slow down in android app? or ...

I'm not sure my question is understandable because of my poor English.

Thanks for reading my question!

There is no flow management on top of NUS Characteristic Value data (Write or Notify) methods. So whatever you need to do (like letting the opposite side know that it must slow down the transfer) you need to define and implement on application layer (in your apps). It's the same as normal wired UART without flow control.
