LPN without friend node

[Gerry]

Hi,

We have one client/provisioner and multiple servers/provisionees (light switch style) in our mesh network.

Now we plan to have a LPN-sensor node (server as above) in that network without using friend-nodes.

The sensor should wake up once every minute, send a message to the client, stay up for 5 sec. and then sleep again.

1. What changes to the server would be necessary to achieve that?

2. Is it possible to use LPN without friend-nodes?

regards

Gerry

So far, I only tried to do so in the main loop. Do you think it makes a difference, when I do it in a timer interrupt?

How? Are you using nrf_delay(ms); for that?

Hi. 

Got a tip from one of my colleagues. He suggested that you might be able to solve this by having your node advertise as a regular BLE-beacon and having some nodes in the mesh network listening for the beacon advertisment. 

You can take a look at the Enocean example in our nRF5 SDK for Mesh, which does something like this. 

EDIT: Updated documentation link:

No, I count, when I get out of sd_app_event_wait(). Happens about once a second. After 10 sec. I switch off, after 20 sec. on again for the test.

Hi,

Your documentation has moved? could you kindly update that link?
