I need to connect ESP32 BLE to heart rate sensor (uses heart rate monitor gatt service) and send about 100 bytes data over wifi every 15 seconds. After reading the above posts it sounds like this would be possible to do, I'm I right? Thanks, Tipo But at that time, Do you need WiFi to keep running a...
