Problem application bluetooth don't send character and display Error 507 on app with mbed program

Hello,

I've got a problem with this program I can't send a character with an application btle "Error 507" Displayed on the app.What's the problem?

infinite loop while (true) { check for trigger from periodicCallback() if (triggerSensorPolling && ble.getGapState().connected) { triggerSensorPolling = false;

Do blocking calls or whatever is necessary for sensor polling. In our case, we simply update the HRM measurement. hrmCounter++;

60 <= HRM bps <= 100 if (hrmCounter == 100) { hrmCounter = 60; }

update bps hrService.updateHeartRate(hrmCounter); } else { ble.waitForEvent(); low power wait for event

} } } Serial BT(PA_2,PA_3); tx, rxb Serial pc(USBTX, USBRX); int main(void) { pc.baud(115200); BT.baud(115200); Ticker ticker; ticker.attach(periodicCallback, 1); blink LED every second

BLE::Instance().init(bleInitComplete); { while (BT.available() > 0) { read the incoming byte: char incomingByte = BT.readable(); printf("I received:"); BT.putc(incomingByte);

} } }

Thank you for your answers.
