Hi all
Has anyone seen an industrial whatever???? device to detect phones via bluetooth? We want to initiate something on the plc when one of our phones are in the area? there are three in our area and want to know if 1,2 or all three are here?
Would also be happy with suggestions using some kind of tag we can add to our keyring etc.
