Bluetooth LE set_advertisement with flag and service_data

[PhS]

I try to make BLE beacon app and listener with no connection.

I've develop an Android application who send BLE beacon no_connected, she work well and my LoPy receive and decode correctly all beacon.

I try to develop the android application on a second LoPy, but I've some problem with the pycom bluetooth library.

Only service_data in set_advertisement

When I try to advertise in bluetooth with my LoPy, if I add only service_data in the bluetooth.set_advertisement, no data was send, when i start the bluetooth.advertise ( checked with a UberTooth )

bluetooth.set_advertisement(service_data=srv_data)
bluetooth.advertise(True)

If I use only the manufacturer_data, all my data was sent correctly but not in the good container ! ( checked with a UberTooth )

bluetooth.set_advertisement(manufacturer_data=srv_data)
bluetooth.advertise(True)

How I can send only service_data in the BLE advertise ?

Set flag value in in set_advertisement

I use another Lopy to receive data sent by my LoPy advertiser
But the flag in the data have a bad value (6) not referenced in the docs.pycom.io.
How, i can set the flag value in bluetooth.set_advertisement ?

Thanks
