Hi developers,
I would need some help, as I am fighting since 2 days on a simple problem.
I used the Nordic BLE example:
https://github.com/fabiobaltieri/ciq-nrf-blinky
as a template for my BLE project.
Now I run into the problem, that the device name is not reported by BLE scan result. This is a known issue in the SDK:
As a workaround I want to compare the UUID instead of the device name in my project, as the UUID is found in the BLE scan correctly.
=> But how to compare the UUID provided via getServiceUuids() against a fix value?
Sounds simple, tried many times with printf debugging (log), no solution found.
Some code snippets:
function initialize() {
SERVICE = Ble.stringToUuid("19067010-db9e-4075-a5b5-e6df36619906");
READ_CHAR = Ble.stringToUuid("19067011-db9e-4075-a5b5-e6df36619906");
READ_DESC = Ble.cccdUuid();
WRITE_CHAR = Ble.stringToUuid("19067012-db9e-4075-a5b5-e6df36619906");
SCAN_TIMEOUT = 5;
RESCAN_DELAY = 10;
BleDevice.initialize();
}
function onScanResults(scanResults) {
debug("scan results");
var appearance, name, rssi, rawdata;
var mfg, uuids, service;
for (var result = scanResults.next(); result != null; result = scanResults.next()) {
if (result instanceof Ble.ScanResult) {
appearance = result.getAppearance();
name = result.getDeviceName();
rssi = result.getRssi();
mfg = result.getManufacturerSpecificDataIterator();
uuids = result.getServiceUuids();
rawdata = result.getRawData();
debug("device: appearance: " + appearance + " name: " + name + " rssi: " + rssi);
debug("result raw: " + rawdata);
debug("Vor matchDevice");
if (matchDevice(name, mfg, uuids)) {
//if (appearance==4660) {
connect(result);
return;
}
}
}
}
protected function matchDevice(name, mfg, uuids) {
//dumpUuids(uuids);
//dumpUuids(UUID_COMPARE);
//dumpMfg(mfg);
// if (name != null && (
// name.equals(DEVICE_NAME) ||
// name.equals(DEVICE_NAME_Z))) {
// return true;
// }
var uuidString = uuids.String;
debug("SERVICE: " + SERVICE);
debug("uuidString: " + uuidString);
if (uuids.equals(SERVICE)) {
debug("matchDevice: Found");
return true;
}
debug("matchDevice: NOT Found");
return false;
}
Main question is on line 53 the does not work....
Thanks for support.
Best Regards Sven
