    I'm not aware of anyone on the forum using nRF24L01 transceivers as active RFID tags.

    I wasn't aware they were used this way until I saw one of your earlier posts. Your earlier post caused me to look around the internet for information and I found this site.

    OpenBeacon

    Have you seen it? It looks like it would have the information you're looking for.

    Thanks for your reply.If the multi tags trasmitts at a same time the receiver can response as a single tag.So we set a corresponding time slot in every tags for transmission.

    That's the same solution I used in my panic button project. Each device had an assigned ID number and could only initiate communication in predetermined time slots.

    BTW, I'm glad you asked about the nRF24L01 being used in active RFID tags. I hadn't know about this application prior to your questions. I think it's an interesting application.

    What microcontroller are you using on your tags?
