Description

Milesight sensors support reading and configuring via NFC. This article describe how to solve the issue of failing to read via NFC.

Solution

Tip 1. Check whether your smart phone supports NFC. If not, please change another available one or use PC version ToolBox. You can also contact Milesight to purchase NXP-PN532 type NFC readers to read and configure Milesight devices.

Tip 2. Check the places of the NFC chip in the phone, and attached it to the sensor’s NFC chip closer enough.(NFC area can be checked via user guide)

Tip 3. Keep the handheld phone still while reading.

Tip 4. Check if the battery is installed well, if there is an insulating strip in the battery slot, please remove it. We have insert that in part of the sensor products to meet the logistics request.

Note: Please refer to quick guide in equipment packaging box to check whether your sensor have an insulating strip.

Tip 5. For EM300, there are two battery slots but one battery, you can move the battery to another slot, then check it once more.

EM300 sensor has two battery jars. The standard version of EM300 sensor comes with only one battery. In that case, battery is installed as shown in the picture below. NFC chip is on the back of that battery jar.

For some models of smart phone, NFC connection may be interfered by battery. Therefore, you can put the battery in the other jar and try again.

Tip 6. Connect the sensor to PC’s USB and check if the sensor is fine. If both NFC and USB connection don’t work, please contact Milesight support to process.

Note: for EM500 series product, please follow below steps to shortcut the capacitor:

(1)Disconnect the senor from PC and pull out the battery;

(2)Using a mental cable to shortcut the capacitor for a few seconds (at least 5s);

(3)Connect the sensor to PC again (battery not back) to check if USB port is recognized.
