Mesh LPN switch example - High current

[Shahin97]

Hello, 

Running on the latest 2v7 release 2 light switch examples, one running the lpn overlay and the other without. Creating a scenario with lpn node and a friendship node, provisioned via the android app. The LPN node is consuming 220uA, which is rather high, I have seen this in the double digits several months ago so I believe a change in the sdk has caused this high current. I will roll back and see if I can get the low current that I have previously seen before. 

Setup:

2x nrf52832 dev kits - rev3.

mesh_light_switch example, 1 with overlay-lpn.conf,

the other with CONFIG_BT_MESH_FRIEND_LOG_LEVEL_DBG=y to verify the friendship. 

Current measured through the nrf current measurement pin headers,

Note: the bt_mesh_proxy_identity_enable() does not change the current consumption

Thank you, 

Shahin.

Publisher field is required for one or more models to be in low power mode.

Hi cyriactoms,

Your question is quite unrelated to the topic being discussed here. In the future, for such thing, please open a new case instead. We intend for each DevZone thread to focus on one technical topic only.

overlay_lpn.conf is what known as a Kconfig fragment.

If you are using the command line to build, use the EXTRA_CONF_FILE argument as explained here: Adding files and configuring CMake (nordicsemi.com).

If you are using the nRF Connect for VS Code extension, when adding or editing a build configuration, add the file in the "Extra Kconfig fragment" menu.

For further questions, not on the topic of the opening post, please open a new case.
