RPI 3 using noble library to read packets of nRF5 SDK for Mesh ver 0.9.2

[ayman]

I'm developing a BLE gateway/scanner for nRF5 Mesh BLE network, my system components are as following:

• Raspberry Pi 3 installed with noble nodejs library (as I'm familier with noble, you can suggest any other library).

• nRF SDK Mesh ver.0.9.2

• Two custom nRF52832 boards. I ran light control client/server demo application on my custom boards, and it's working fine, that client switch on/off server leds, I know it must be at least 3 boards for true mesh, but this is not an issue, I just want to read these mesh packets on my RPi3, get its data, so I can relay this data to a cloud service. my noble simple code as following;

  noble.on('stateChange', function(state) { console.log('state has changed', state); if (state == 'poweredOn') {
  noble.startScanning([ ], true, function(error) { if (error) { console.log('error starting scanning', error); } else { console.log('started scanning'); }

  noble.on('discover', function(peripheral) {

          console.log('discover event hit', peripheral.advertisement);
  

I get empty data, how to decode/read mesh data using noble or whatever tools on RPI, any suggestions?

Thanks

Hi,

I'm not familiar with Noble and nodejs. Nor were the guys in the Mesh team and they suggested that you have a look at the Interactive PyACI example and control your device(s) throught that and a COM port.

But Interactive PyACL has to interface mesh beacons through serial port, could I use it to sniff mesh packets using RPI3 built-in bluetooth chip

[ayman]

Is there any way I could follow in order to use RPi3 as a gateway for mesh network, a way where RPi 3 could read and understand these mesh packets.

Based on this question it sounds like you have figured it out?

[ayman]

yes, you're right.
