Hello everyone,

for my project I want to use the SPSGRF-868 Module. I want to know if is it possible to use the module as point to multipoint?

My goals is to have a Master that transmit data to two Slaves, and that only one at a time answers if it is interrogated.

Thank you

Paolo

Hi Paolo,

Yes. It is possible.

Please just configure them with same RF parameters.

Basically it will be broadcasting: one device send a packet and others shall be able to receive the packet.

Best Regards,

Winfred

Hi Winfred,

   thank you for reply.

But how do I configure the RF parameters in the module?

I looked at the datasheet but did not find anything about it.

Some suggestion, please...
