It was noted on the mailing list that the changed retransmission timeout calculation in commit 1a28b3 may yield to inefficient code on embedded systems which have no fpu. This change now uses fixed point arithmetic instead. By default, it represents ACK_TIMEOUT and ACK_RANDOM_FACTOR as Q2.6 numbers and uses Q0.8 for the randomness parameter. The resulting timeout value is represented in system ticks (i.e. a multiple of COAP_TICKS_PER_SECOND) as an unsigned integer.

ABOUT LIBCOAP
libcoap is a C implementation of a lightweight application-protocol for devices that are constrained their resources such as computing power, RF range, memory, bandwith, or network packet sizes. This protocol, CoAP, is standardized by the IETF as RFC 7252. For further information related to CoAP, see http://coap.technology.
