Hi, i Will make a Gateway that contains a nRF52 BLE board and Wifi esp8266 module. The Pulse oximeter should send data to the nRF52 over BLE, and then the nRF52 should send it forward to the Wifi module.
ex: if the Puls oximeter is going over 150, the nRF52 should recive data (over BLE) and send a "Alarm" to the WIFI module that sends a mail.
