Hi,
I have two Edison to explore BLE.
One device should take the role of central, the other one has peripheral.
On the peripheral, I use the Bleno.js lib with the echo_example.js code from https://github.com/sandeepmistry/bleno/tree/master/examples/echo https://github.com/sandeepmistry/bleno/tree/master/examples/echo
Starting it looks good:
bleno - echo
on -> stateChange: poweredOn
on -> advertisingStart: success
On the central,, I use the Noble.js lib to scan for services.
It gets discovered from my laptop:
$ node simple_scan.js
poweredOn
{ localName: 'eddie2',
txPowerLevel: undefined,
manufacturerData: undefined,
serviceData: [],
serviceUuids: [ '1fffffff4ffff4fffffffff2ffff4ff3' ] }
But then discovering the services (see scanning code https://github.com/embeddednodejs/ch_10_physical_internet/tree/master/simple_scan ch_10_physical_internet/simple_scan at master · embeddednodejs/ch_10_physical_internet · GitHub, it results on my laptop in:
$ node scan_services.js
poweredOn
found device: eddie2
services: 1fffffff4ffff4fffffffff2ffff4ff3
found device: undefined
services:
xpcError: connection interrupted
Trying the same Noble scripts on the other Edison gives:
root@edison:~/simple_scan# node simple_scan.js
And then nothing happens.
How can I detect the eddie2 peripheral?
Thanks a lot for your help!!
