How to connect the "proxy server" of example "light_switch" in nrf5_SDK_for_Mesh_v2.0.0 with mobile phone ?

[Bomin Lin]

I have downloaded "nrf5_SDK_for_Mesh_v2.0.0" yestoday, and try to setup the "light_switch" demo with 3 pic nRF52 DK.

According to the document description, “proxy_server” can provide GATT services after the configuration is completed.

After I start the demo and complete the configuration, I can find the Bluetooth broadcast signal, but when I use the phone to connect to the device, the program will assert.

I want to know how to use mesh's "proxy node" feature in light_switch example.

Hi,

Thank you very much for reporting this issue. It is highly appreciated! I am sorry for the delay from our side.

I have reproduced similar behavior using nRF Connect for desktop.

I found that the light switch proxy server example asserts with a SoftDevice assert on pc 0x12a42 whenever I expand the services for the device listed in nRF Connect after successfully connecting.

I have reported the issue to the Mesh team, and they will look into the issue.

Hi,

The problem is that the mesh stack does not release the timeslot in time.

For now, a workaround is to increase the following define on line 65 of timeslot.h:

/** Allocated time between end timer timeout and actual timeslot end. Should be
 * longer than the longest global IRQ lock in the system. */
#define TIMESLOT_END_SAFETY_MARGIN_US (100UL)

Edit: The workaround proposed here did not solve the issue and can be disregarded. See the workaround in my other answer instead. TIMESLOT_END_SAFETY_MARGIN_US of 100 should be sufficient.

The BLE GATT services which "Proxy_client" offered have any features? Why does the device disconnect immediately when I write data in GATT services?

Hi,

The GATT service on the proxy server functions according to the Bluetooth Mesh specification. (It is the same proxy server feature on both proxy projects in the ligth switch example, i.e. both for light switch client and for light switch server.)

As previously noted we have an early version of an iOS library for the proxy client.

We are looking into why in some situations the device asserts. Unfortunately I do not have a clear answer yet for why that happens.

Hi Tesc, if a phone works as a central device it means that If I have already central devices deployed using a nRF52832. Can I use "Proxy server" to connect them a Bluetooth Mesh?

I am sorry for the off topic

hi Bomin Lin

Are you able to send ON to Mesh Server  Via  Mesh Proxy Data In  on Mobile ?
