How to send a "Select Application" command to M24SR?

Lxuan.1391 · ‎2019-11-19

Hello, I`m using M24SR64 to config wifi using I2C on Raspberry Pi.

And now I have a problem that after conmunicating with M24SR64 by I2C, and deselect I2C session, I found the RF session is closed too. I want to use Android App to config NDEF message after deselecting I2C session. I found in the datesheet that "An RF session is taken when M24SR64-Y receives a valid Select Application. " but I didn`t find the "Select Application" command.

Can anybody helps me out?

Thank you very much!

Dear Customer,

The Select Application command that is referred to corresponds in fact to 'NDEF Tag Application Select command' described in paragraph 5.6.3 of the M24SR64 Datasheet.

The functional procedure 'Selection of an NDEF message' described in section 8.1 gives in fact the whole sequence of steps to be followed by the mobile phone (or the I2C master) to gain access to the NDEF message and be able to read it.

Have a good day.

Regards
