Custom BLE packets on mesh network

[AndyM]

Hello

I have a mesh node that needs to broadcast a custom BLE packet

To start advertising I call bt_le_adv_start and it works as expected.

I'm curious about the error that I see in the RTT log

00> [00:08:41.658,050] <dbg> bt_mesh_net: bt_mesh_net_relay: Relaying packet. TTL is now 9
00> [00:08:41.658,172] <err> bt_mesh_adv_legacy: Advertising failed: err -120

My understanding is that his is because my app started advertising and the mesh network cannot relay the packet

I tried to call 

bt_mesh_relay_set(BT_MESH_FEATURE_DISABLED,BT_MESH_TRANSMIT(0,1));

before calling bt_le_adv_start  but I get same error -120.

What's the proper way to disable mesh relay?

Is there a way for custom advertising and mesh relay to coexist in a provisioned mesh node?

Thank you

Hi,

Could you provide me with what SDK version you are using?

The error is probably due to you running BLE and Mesh at the same time.

custom BLE packet

Can you elaborate what you mean by custom?

We do have an example in the nRF Connect SDK that shows how you can run BLE and Mesh concurrently. I suggest you have a look at this example and use that as a reference.

custom = packet type is BT_DATA_MANUFACTURER_DATA (0xFF)

SDK is 1.9.1

I'll take a look at the sample - looks like it does what I need

Thank you

I use  Zephyr SDK 1.9.1

Could not find this sample in the SDK or the full zephyr repo which I cloned

Could you please point me to the location of this sample? 

Thanks

Just enabling  CONFIG_BT_EXT_ADV causes the program to crash

Any suggestions?

Thanks
