Add these lines to prj.conf to see printk output in SES Debug Console:

# Config logger

CONFIG_USE_SEGGER_RTT=y

CONFIG_RTT_CONSOLE=y

CONFIG_LOG_BACKEND_UART=n

CONFIG_SERIAL=y

Hi,

Most of the earlier questions you posted should be solved by switching to nRF5340DKs. The nRF5340PDKs are preview kits and are deprecated for the later versions of NCS. The first thing would be to go over to the nRF5340DKs.

Unfortunately, we do not have any mesh specific guide for the nRF5340, but the nRF53 User Guide has a lot of setup information that is helpful.

[quote user="new"]I lately found that mesh light control, mesh sensor client, mesh sensor server not supported for NRF5340 and got disappointed. I expected those features for NRF5340. Do these examples support NRF5340 in the future connect SDK releases?[/quote]

[quote user="new"]Is there any exchange program for NRF5340DK with NRF5340PDK?[/quote]

As for future roadmap questions and exchanging PDKs for DKs, I suggest you contact your RSM(Regional Sales Manager) about this. You can do this by using this link: Contact Us and make a a ticket under "Sales Related questions".

We are very much disappointed with the way NRF5340 has been released with incomplete support.

Being unable to set up the BLE Mesh light switch and incompatible PWM example for NRF5340PDK v0.8.0, we tried custom PWM.

Later we got to know even PWM3 is also not available in NRF5340PDK and fixed in a later release.

We ordered 4 NRF5340, knowing that all BLE Mesh examples, PWM is supported, but nothing is working and issues are seen later.

Is there any exchange program for NRF5340DK with NRF5340PDK? We need a minimum of 4 PWM, 2 SPI, and 2 I2C instances to get started with application building. But unsure of what to do with this deprecated NRF5340PDK.

Thank you for the quick support.

I lately found that mesh light control, mesh sensor client, mesh sensor server not supported for NRF5340 and got disappointed. I expected those features for NRF5340. Do these examples support NRF5340 in the future connect SDK releases?

Even after "CONFIG_SERIAL=y" mentioned in Proj.conf; I am unable to see the printk - output in the embedded studio debug window. However, using PUTTY, I get the "printk" logs. Is there any setting required to see printk output in the embedded studio?

Hi,

Answering your initial post:

A correction to the thread I referred to in my previous reply. It seems like after NCS v1.4, Mesh samples should run with the default config on the network core

Note that the Bluetooth: Mesh Light Control example does not support the nRF5340. This is not an issue with the mesh stack itself, but the way the sample interacts with the hardware.

[quote user=""]how to reset the mesh light back to an unprovisioned state after once provisioned.[/quote]

You can reset the device to an unprovisioned state by calling bt_mesh_reset().

[quote user=""]If we are using nordic BLE sample examples 'light, light control, light switch', is there any guide that how to add more resources such as SPI/i2c, ADC to the same.[/quote]

There are no specific guide for this but perhaps look at the zephyr documentation, including the devicetree guide, and the device model. There are a lot of samples on driver usage both in NCS and Zephyr, those are a good starting point. There's nothing about the mesh stack that should interfere with the HW drivers.

[quote user="new"]Also, how to see debug output in nordic specific embedded studio for NRF_CONNECT_SDK examples. No RTT settings seen and project options are disable or un-selectable (greyed out).[/quote]

Try adding "CONFIG_SERIAL=y" to prj.conf.

I will come back to you regarding the other questions soon.

Thank you for the reply.

Again an elaborated question.

We bought NRF5340 PDK - v0.8.0

The getting started guide available is not connectable with respect to the compatibility of hardware, software.

Question 1: What is the difference between NRF5340PDK vs NRF5340DK. We ordered last week and got delivered PDK. But in NRF connect SDK v1.4.99-dev1, sometimes it shows nrf5340PDK board is deprecated.

Question 2: How to get started with NRF5340PDK, and what are the examples tested and supported for the board. In the PDK, we can run blinky but not blinky_pwm. The nrf_connect_sdk option in segger embedded studio often throws cmake_error when selected NRF5340PDK for BLE mesh light examples.

Question 3: Does BLE Mesh supported in NRF5340PDK? Only mesh light example is flashing but not, BLE Mesh Light control or BLE Mesh Light switch. Error: Unsupported board, CPU unable to halt, CMake error for selecting NRF5340PDK.

Question 4: How to configure device tree alias for NRF5340PDK. Either overlay file is not found or editing DTS file not affecting any changes. For some examples using the board name NRF5340DK works, and for some other NRF5340PDK. What is the suggested configuration for NRF5340 v0.8.0?

Question 5: What is the actual difference between NORDIC BLE mesh vs Zephyr BLE mesh setup. How to chose a nordic soft device for NORDIC BLE Mesh examples? Does there any setup guide available for BLE Mesh in NRF5340PDK.

Question 6: What are the necessary fundamental kernel or RTOS or soft device architecture knowledge expected for developing a BLE Mesh application on NRF5340. It is very hard to set up even the sample examples and unable to resolve any build errors.

Question 7: Guide me to the resources to actually choose the right combination of NRF_connect_SDK for NRF5340 v0.8.0; replication configuration of the other board setup does not work for all examples.

Hi,

I will ask the mesh team to give a comment on this.

You can have a look at this thread.
