G4 can't find Bluetooth device

[Lagoon_75]

I have a Marantz NR 1504 Home theatre amp that has a blue tooth "dongle" which supports A2DP bluetooth streaming. My Samsung Galaxy Note Pro finds it and connects no problem, as does my wifes Samsung Tab, however it does not show up on either mine, nor my wifes Moto G4 when scanning for available devices.

I should add that both 'phones have no trouble in finding and connecting to all our other bluetooth devices, it is just the Marantz that they cannot find. I've tried the usual re-booting and safe mode, but neither phone can "see" the Marantz.

Any thoughts any one?

Cheers,

Cliff

Ignore this. It transpires that the blue tooth module of the Marantz is a bit "flakey" and does not always go into pairing mode when it should. After persistent re-tries this morning, I finally got it to work.
