otPlatSettingsWipe undefined reference error

[Rohit Rajapure]

Hello All, 

I am developing thread base system. 

I am using SDK - nRF5_SDK_for_Thread_and_Zigbee_v4.1.0_32ce5f8

Dev-kit - nrf52840

I am using mtd code for development of my product. For requirement I need to follow these 4 steps to join network 

1 factory reset

2. ifconfig

3. Joiner start XXXX

4. thread start. 

So, I have modified the mtd code as per my requirement to auto configure the above commands using API. 

I am able execute "ifconfig", "Joiner Start XXX" and "thread Start" using respective APIs in main file. (Without entering CLI).

But If I use "otPlatSettingsWipe" API to factory reset I am getting "undefined reference to `otPlatSettingsWipe'"  error. 

Can anyone help how to resolve this issue ? or for Factory reset is there any other function?

I am following CLI command flow to execute using API's 

Thanks in advance 

Regards,

Rohit R

Hi Rohit

Is the function otInstanceFactoryReset what you are looking for?

Hi Sigurd Hellesvik,

Sigurd Hellesvik said:

- Okay, I read about this api and description looks similar. 

What I need is like how cli-mtd works using commands

1. factoryReset

2. Ifconfig 

3.Joiner Start

4. Thread start 

I want same sequence should execute using respective APIs. So I followed same this 1. Factory reset before thread_init() but I am unable execute while() loop of main function. 

If I comment otInstanceFactoryReset() then everything works perfect.

Can you help to execute in sequence. I need this sequence so. 

Thanks and Regards

Hi

otInstanceFactoryReset will wipe the persistent storage, and then restart your program.
Since you call reset each time you reset the program, this will create a reset loop.

otInstanceErasePersistentInfo() will only erase persistent storage. Is this what you want to achieve?

- yes, correct. when I repower or reset the board first it should erase and then do the ifconfig, joiner and thread start. 

We want to emulate the factoryreset command from MTD CLI example to complete joining process in unattended mode and not with user intervention as in cli mode

- I tried the otInstanceErasePersistentInfo() function but still same unable to execute erase process it. when I reset or repower it directly wait in thread start mode and LED1 blinks ( as there in cli-mtd code).

let me know what is the problem. Attached is the main file.

Hi

First, the otInstanceErasePersistentInfo() will erase info for an instance. Therefore, you most likely need to call your FactoryReset function after thread_instance_init().

Is the LED1 blinking slow or rapid? See Thread BSP LED and button reference.
