send data over uart without losing connection

[Deepak Kumar]

hi all, i have a electronic device having a button which sends continous data till i keep button pressed. i want to send these data without losing connection. i can across this tutorial where it is written that i can send data using ble_nus_c_string_send() function this function can only be used 2 times per connection interval (minimum 7.5 ms). If I call this function too fast, the tx buffers fill up and you will be returned the error BLE_ERROR_NO_TX_BUFFERS.

how i should handle this situation so that if i keep my button pressed which gives multiple data and need to send data without connection lost.

Please kindly guide me with some example or something.

thanks!!

You need a buffer (or "queue") to hold the data that's awaiting transmission.
