Is Transceiver Dev Node-nRF2401A a good Gateway?

Hi all,

I am thinking about a project where there are a central dektop with a Transceiver Dev Node-nRF2401A connected to its COM1 port

and arround it there will be about 100 or 200 or even 300 nodes.

All those nodes will embedded an ATMEga128L with a Transceiver nRF2401A Module Trace Antenna driven by bit banged approach.

All those node will sense temperature and batery level. Yes, a very dense network. A tipical scenario will be a small floor of a building.

Communication will be done by pooling, this means that it is the desktop that will ask, one by one node, their temperature and bat level.

My question is:

Does Transceiver Dev Node-nRF2401A supports 365 days per year, 24 hours per day of working?

Can I rely on it for a reliable gateway? Or it was built only for test cases purposes and nothing more.

What about addresses for all the nodes. Can this technology supports addresses that are different from others in just a bit or the system will be confused.

Thanks you

I’d lean more towards developing something new rather than use that module. SFE has good quality designs, but that “com-port-parasitic-power” trick makes me nervous.

Please, define “com-port-parasitic-power”?!

I am using it and till now no problem…

Ok, but what is your solution?

I need it for a gateway, so I just can see one way for communication between PC and nRF2401 antenna, which is via serial communication. So, there will be always a db9 port, right?

If were you, what do will you do? get some PCB, put an ATMEL, a nrf2401 and a db9 and bit bang the nr2401?
