Abstract
A BLE-Mesh device includes a controller, an RF driver for driving the transceiver adapted to be coupled to an antenna, and a counter. The controller implements an applications layer including BLE and Mesh Applications, and a BLE stack and a mesh stack. A redundant traffic suppression relaying algorithm is for waiting for a random time within a selected time window from W1 to a later W2 before attempting to transmit a first packet that contains a unique source (SRC) address and a packet sequence (SEQ) number of a device that is the source of the first packet. If during the random time a packet with both the source device's SRC address and the SEQ number is received, the counter is incremented from an initial count to a current count. After the random time elapses, the current count is compared to a Cthreshold value, and the first packet is transmitted only if the current count<the Cthreshold value.
