Unable to use GATT server with central role #326

Open bradjc opened 7 years ago

bradjc commented 7 years ago

I'm trying to use noble and bleno together in a single application to allow linux to be in the central role but also be the GATT server. I actually have this working, but had to remove an if statement in bleno. Namely, I had to remove this if:

BlenoBindings.prototype.onLeConnComplete = function(status, handle, role, addressType, address, interval, latency, supervisionTimeout, masterClockAccuracy) {
  // if (role !== 1) {
  //   // not slave, ignore
  //   return;
  // }
  ...
}

from here.

With that if the AclStream never gets set up and bleno never responds to discover services requests (or any other request).

I understand why that check is there, since a connection callback is valid in both the central and peripheral contexts, however, I believe a GATT server is equally valid in both contexts. Any thoughts on this? Would an environment variable be the right approach to skip that check in cases like mine?

I use bleno and noble to develop node-fitbit-livedata module for getting live data from fitbit devices. I also have met this problem when these modules work on Raspbian.

This workaround is useful for me.
