Transmite Eddystone URI and UID data simultaneously

[danielcbit]

Hi, I'm playing with Eddystone examples for nRF 8001 and I saw that in the current code you can transmit only one type of payload. How would I accomplish transmitting them "simultaneously"(change the advertising payload at each publish)?

Hi @danielcbit,

I think you can try modifying the Eddystone beacon code to call toggle between the following

• UID: https://github.com/sandeepmistry/arduino-BLEPeripheral/blob/master/EddystoneBeacon.cpp#L48-L64
• URL: https://github.com/sandeepmistry/arduino-BLEPeripheral/blob/master/EddystoneBeacon.cpp#L73

after calling begin.

Since the advertising interval is 100ms, you'll have to toggle at a less frequent interval than this.

I'm closing this for now, feel free to continue the discussion though. Pull request welcome for the new example along with setUid API to make things cleaner.

Hi @sandeepmistry. I would have to toggle between those in the loop method, right?

[sandeepmistry]

I would recommend it, two options for delaying are using:

• delay(ms)
• checking the value of mills() and comparing differences.

[danielcbit]

Only mils() actually, since delay() stops the code execution so it is not a good idea.

Nice, I'll work on these patchs. I will add support for ESP8266 as well, I have a patch already. This is my current platform.

@danielcbit sounds good, looking forward to seeing your patches.
