Good morning all,
I will need your advice regarding the feasibility and stability of a project.
I have already created a first project which works well.
A portable external NFC reader on battery:
I have an arduino uno card coupled with an NFC shield which reads the NDEF message from an NFC TAG and transmits it by bluetooth (HC 05) to a tablet.
I would like to extend this project with other NFC readers which would all send to the tablet.
I am wondering about the wireless transmission between other NFC readers and tablet
Solution 1 considered: Keep the Bluetooth transmission but transform it to BLe to allow several BLe to be connected to the tablet. The disadvantage lies in the configuration of the application which is more complicated for the user and the short range
Solution 2: WIFI but supposes to have an already existing WIFI network and therefore the installation of a mini router for example
Solution 3:
Go through the radio frequency
The main NFC reader is always connected in BT to the Tablet.
The secondary readers (2,3,4) transfer the result of the scan to the main reader (1) in RF.
Reader 1 transfers in BT (as currently) to the tablet ... (its scan and the NDEF messages received by RF
I hope not to be too confused in my explanations because it is not easy to explain ... I put a small photo to illustrate.
Do you think solution 3, RF is reliable and can send to MASTER reader?
Thanks in advance for your help and for reading this post.
Ced
