Reply to "Improving range of LionCheif with Bluetooth locomotives?"

Don't you also have the issue that both ends have to be using BEL5 in order to realize the increased range?

Yeah…. That should be true. 802.15 specifies legacy modes so your BLE5 modem will revert if it’s paired with an endpoint that doesn’t support it. The pairing exchanges let the two endpoints specify which link mode to use.



I’m thinking about buying like a ZVA183 S+ PA and sticking it in the remote and locomotive to bring up the transmit power. Since BLE is a TDD system (not transmitting and receiving at the same time) you should be able to solder the amp feed to the pcb antenna directly without needing to access in front of the diplexer. 2.4 GHz is an ISM band so you don’t need a license up to 1W of EIRP.
