Set range of CAN identifiers to block via acceptance filter
filterBlockRange(canch, rangestart, rangeend) blocks messages within a given range by setting an acceptance filter. You can use this function with Vector devices only.
The CAN channel that you want to set the filter for.
The first identifier of the range of message IDs that the filter starts blocking at.
The last identifier of the range of message IDs that the filter stops blocking at.
You can set the filter to block or accept messages within a specific range.
canch = canChannel('Vector','CANCaseXL 1',1) filterBlockRange(canch, 500, 750) filterAcceptRange(canch,600,625) filterAcceptRange(canch,705,710) filterBlockRange(canch,1075,1080)
You can configure message filtering only when the CAN channel is offline.
CAN message filters initialize to fully open.
filterReset makes the acceptance filters fully open.
filterBlockRange supports only standard (11-bit) CAN identifiers.
You must set the values from rangestart through rangeend in increasing order.
filterBlockRange and filterAcceptRange work together by blocking and allowing ranges of CAN messages within a single filter. You can perform both operations multiple times in sequence to custom configure the filter as desired.
