Unable to register a beacon due to Invalid field value for "advertisedId.id"

I have obtained OAuth Access token with th following scope: https://www.googleapis.com/auth/userlocation.beacon.registry

And using the access token received for authorizing Proximity Beacon APIs,

Now when I tried to register a beacon with the value mentioned at google's documentation page, It throws an error as follows,

{
error: {

Solution

  • The AdverisedId you pass to the register call must be valid — for Eddystone compatible beacons, the id field must be a 16-byte binary ID directly encoded as a base64 string, with the type field set to "EDDYSTONE".
