I am in the process of developing a BLE scan module on nodeJs using Bluez. Below is the code snippet I have implemented:
exec('sudo hcitool lescan --duplicates &', function (error, stdout, stderr) { });
exec('sudo hcitool lescan --duplicates &', function (error, stdout, stderr) {
var result = exec('sudo hcidump --raw &');
/*
* This recursive function fetches raw data from hcidump and passes it to createBeaconDevice function.
*/
result.stdout.on('data', function (data) {
var currentDate = new Date();
writeLog('scanData', data, currentDate.toISOString().replace(/T/, ' ').replace(/\..+/, ''))
createBeaconDevice(data);
});
});
Unfortunately, the issue I am facing is that the functionality stops working after some time without any warning or error messages. Can anyone suggest what might be causing this problem? Any help will be greatly appreciated.
