  368. * The application is free to choose whether to call this function from thread mode (main context) or directly from the

  402. * available for a connection. Please note that this does not return the number of free packets, but rather the total
  403. * amount of them for that particular connection. The application has two options to handle transmitting application packets:
  404. * - Use a simple arithmetic calculation: after connection creation time the application should use this function to
  405. * find out the total amount of guaranteed packets available to it and store it in a variable.
  406. * Every time a packet is successfully queued for a transmission on this connection using any of the exposed functions in
  407. * this BLE API, the application should decrement that variable. Conversely, whenever a @ref BLE_EVT_TX_COMPLETE event
  408. * with the conn_handle matching the particular connection is received by the application, it should retrieve the count
  409. * field in such event and add that number to the same variable storing the number of available guaranteed packets. This
  410. * mechanism allows the application to be aware at any time of the number of guaranteed application packets available for
  411. * each of the active connections, and therefore it can know with certainty whether it is possible to send more data or
  412. * it has to wait for a @ref BLE_EVT_TX_COMPLETE event before it proceeds.
  413. * The application can still pursue transmissions when the number of guaranteed application packets available is smaller
  414. * than or equal to zero, but successful queuing of the tranmsission is not guaranteed.
  415. * - Choose to simply not keep track of available packets at all, and instead handle the @ref BLE_ERROR_NO_TX_PACKETS error
  416. * by queueing the packet to be transmitted and try again as soon as a @ref BLE_EVT_TX_COMPLETE event arrives.

  440. * The way that this is accomplished is by extending the grouping mechanism that the Bluetooth SIG standard base
