Send hid command memory leak and nullpointer reference

Open Mendrzec opened this issue 4 years ago • 4 comments

@Mendrzec today I checked the SendData example and I figure out that the send data function doesn't work. So I put the complete output for you:

anyway, I was trying to write another program, so I just send setLED command, I receive just: PS4_L2CAP: [ps4_l2cap_send_hid] sending command: success nothing else happened.

p_buf is ~never freed and~ referenced even if its is nullptr: https://github.com/aed3/PS4-esp32/blob/03f82acd0986de949a00f52421221d709c3c3413/src/ps4_l2cap.c#L102 fyi @JavadRah

Hi @JavadRah, I tried to reproduce the issue using following script called every 50ms in a loop but had no luck so far:

		if (PS4.Down()) {
			PS4.setLed(123, 23, 45);
		} else {
			PS4.setLed(0, 80, 90);
		}

		PS4.sendToController();

It works perfectly for me.

  1. Could you apply following change to https://github.com/aed3/PS4-esp32/blob/03f82acd0986de949a00f52421221d709c3c3413/src/ps4_l2cap.c#L104 and try again:
    BT_HDR *p_buf = NULL; //here

    p_buf = (BT_HDR *)osi_malloc(BT_DEFAULT_BUFFER_SIZE);

    if (!p_buf) {
        ESP_LOGE(PS4_TAG, "[%s] allocating buffer for sending the command failed", __func__);
        return; //here
    }
  1. Could you share your source code?

Hi @Mendrzec ! I wanted to use an I2C module with this library and found some strange bugs. When I turn on the controller and it pairs, I2c can no longer be used and it works in pieces and ESP32 hangs. Otherwise everything works fine when the Controller is not connected.
