Tinyb does not pick up all devices

[mikedanielcpt]

Hi All

Thank you soooo much for taking time to read and reply on my problem.

I have read another post on github that is remotely similar but does not address my issue. I have also been reading many threads on different sites whilst trying to uncover the cause of my problem.

I am using the tinyb java library from Intel get two pi's (3b+ and a zero w) to communicate via BLE.

Using "sudo hcitool lescan" from each pi, I am able to detect the other pi (and 10 other devices in the apartment block). However, when using below code from 3b+ (360 loops with 10sec sleeps in between), i find up to 23 other apartment block devices but not the pi zero w. When comparing the two device lists I noticed that only 1 device (from somewhere in apartment block) is common to both listings. So it seems that tinyb is picking up a ble device, just not my pi zero w.

Furthermore, I am running bluez v5.43. i tried to upgrade to v5.48 and v5.50. Everything seems to work fine during the make process until i run "make -j4". Whilst executing the command, the pi3b+ reboots. See [u]error 1[/u] below. From then the install does not want to continue. See [u]error 2[/u] below.

(reboots or terminates ssh session, depending if ssh used or direct connection to pi via monitor and keyboard)

I am not sure if upgrading from bluez 5.43 will help with detecting my pi zero from 3b+ using tinyb. This is the primary problem i need to solve. Getting to the root of the upgrading problem will be a bonus though if it does not impact the tinyb library function, else it is a necessity.

        for (BluetoothDevice device : list)

            }
            else
            {
                System.out.println("Not match : Target - " + address +" - Found - " + device.getAddress() );
            }
        }

        if (sensor != null)  
        {
            return sensor;
        }

    }
    return null;
}

So made some progress....

I managed to install bluez v5.50....I needed a better power supply which i got. Same issue though, tinyb on pi3+ is not picking up my zero w, even though lescan is .

Hi

I have resolved this issue.

Not come up against this error yet but in case i do, and for any others, can you explain what you done to fix the issue?

thanks
