Hi,
I tried to wake-up PN532 chip from soft-power-down with RF detector active but it didn't work. The circuit I use is quite smilar to the board from Adafruit (https://www.adafruit.com/product/789) Has anyone succeeded in the wake-up?
Do I need a stronger NFC magnetic field?
Best Regards
Minkoo
Hello Minkoo Cho,
Please consider the next points for waking up the PN532 from Soft-Power-Down mode with the RF Field.
- The bit pd_rfleveldet must be set to 0 in the CIU_RFlevelDet register to have the detector active, otherwise it is disabled:
- The bit CIU_wu_en must be set to 1 in the PCR Wakeupen register to enable the RF Field detection wake-up event:
I hope this helps.
Best Regards!,
Jorge Gonzalez

One more question is whether the RF detection Wakeup function will work with the Passive Tag or not

Dear Jorge Gonzalez,
Thanks for your reply. But whenever I read the pin after I set the bit pd_rfleveldet to 0, It only says '1'.
Then, Is this be a hardware problem?
Best regards
