Gateway with ESP32 #881

Open robsonpg opened 5 years ago

robsonpg commented 5 years ago

Hi Mrs. Kolban/Chegewara, I'm working in a ESP32 BLE Gateway to get characteristics of various servers. These servers are smartbands with heart rate measurement and steps. So, the gateway will able to connect in these devices and read these characteristicas every time that are nearby. That is connections are done and undone everytime (people in and people out). I build the gateway object with BLEDevice::createClient for each device that is detected by the BLEScan. That's OK and devices can connect and disconnect but, at the four cicle of the process of connection, ESP32 freeze the main loop. I have tested events and they continue responding.

Let me show below:

I'm afraid that your device has memory leakage problem. Check memory usage, and free memory.
