» RFID1356 08: Set low power mode

This program shows how to set low power mode in RFID1356 module

Required Materials

1 x Waspmote
1 x Battery
1 x Coin cell
1 x RFID 13.56MHz board
1 x RFID 13.56MHz antenna
1 x RFID Tag


- Remember to connect the battery to Waspmote for proper operation.
- Don't write address 0, 3, 7, 11, 15, ... if you are not an advanced user. You could leave your tag unaccessible.
- Address 0 contains the IC manufacturer data. This block has read-only access.
- Address 3, 7, 11 contains the secret keys A and B. Writing in them will change access keys and conditions.
- This example can be executed in Waspmote v12 and Waspmote v15

  // switch on the RFID module

void loop()
  // 1. Set sleep mode
  // 1.1. put RFID to sleep

RFID_08 Example
Your Firmware version is : FF FF FF FF
1. RFID in sleep mode
RED LED switched off
While RFID is in sleep mode --> wait for 20 seconds...

2. RFID wakes-up
RED LED switched on
While RFID is in normal mode --> wait for 5 seconds...
