BLE reconect problem after 18-19 min connection

Posted: Thu Sep 05, 2019 4:07 am
by swargir
Hello.
I have encountered such a problem. My device (ble client) connects to the ble server once every 5 seconds, the rest of the time it sleeps. Each time before going to bed, I disconnect, and after waking up I call the connection.
After 18-19 minutes of work, my application freezes. It only responds to interrupts.
What could be the problem?
Sleep replaced by delay (5000), the problem remains.

Code: Select all

BLEClient*  pClient;    
static BLEAdvertisedDevice* myDevice;        
boolean connected;
...
/*When first connecting*/
pClient  = BLEDevice::createClient();
                        
...
/*In the start Loop*/
pClient->connect(myDevice);
...
/*In the end Loop*/
 if (connected) pClient->disconnect(); 
 esp_sleep_enable_timer_wakeup(5000000); 
 esp_light_sleep_start(); `
...
