@mubassir-mk Why do you wanna use NFC. Does your wrist band have BLE? If yes, you can easily make this application with BLE.

Hi @mubassir-mk, The NFC tag and reader can work only in Shorter working distance up to 10cm only. but Instead of that like @kowshik1729 suggested, you can try the BLE beacons since the BLE is active you need to power the device, but you can buy readymade beacons which can work with iBeacon or Eddystone protocols and it can work years using single coin cell battery.
Do you have any other particular reason to use the NFC?

@kowshik1729 If you are using an external high-speed switch, there is only one one clock generator for both wifi and BLE and the high-speed switch you mentioned is Ultra-Wideband (UWB) 3โ8 GHz from its datasheet
you also check this solution that I shared in the previous post.
@salmanfaris said in BT and WiFi Dual Core simultaneous operation using ESP32?:
There is a special option called โSoftware controls WiFi/ Bluetooth coexistenceโ it can control the ESP32's Bluetooth and Wi-Fi coexistence using software, more details: https://www.espressif.com/sites/default/files/documentation/ESP32_FAQs__EN.pdf
