The low level commands are necessary to recover the RECEIVED_FRAME_POLLING responses.
Indeed, an index is incremented with each reception of a polling response. And when the WaveCard,
instigator of the polling exchange does not await new responses anymore, it sends to its host a first
RECEIVED_FRAME_POLLING command ;and will await a low level acknowledgement to decrease its index,
and to send next RECEIVED_FRAME_POLLING command.
The following diagram describes the operations carried out by the WaveCard following the reception of a
REQ_SEND_POLLING command:
Remark : Whatever values configured in the RADIO_ACKNOWLEDGE parameter, it is not used
during an exchange in polling mode.
