  Thanks for the fast reply.

  I'm currently running on 1V94 with only the code I have posted above.

• Memory Leak at characteristicvaluechanged

  in Puck.js, Pixl.js and MDBT42 • 6 years, 5 months

  

  Hello,

  I am trying to communicate with another device over Bluetooth.
  But everytime I receive a packet on the Puck.js it uses memory and don't release it.
  So after a few packets, the memory becomes less an I get an error Message --> MEMORY_BUSY.
  On the Screenshot you can see how the memory decreases. (it starts a 1800 free blocks)
  After I got the MEMORY_BUSY message it no longer receive every packet, so I miss most of the packets.

  I think there must be a Memory Leak in the "characteristicvaluechanged" function
  Do someone have simular problems and have found a solution for this problem ?

    NRF.connect("00:13:43:0A:EE:79").then(
      function(d) {
        print("connected");
        device = d;
        return device.getPrimaryService("180D");
      }
    ).then(
      function(s){
        service = s;
        return service.getCharacteristic("2A37");
      }
    ).then(
      function(rd){
        read_char = rd;
        read_char.on('characteristicvaluechanged­', function(e) {
          print("received");
          print(process.memory().free);
          event = e;
        });
        return read_char.startNotifications();
      }
    );
