OK - so long as you have fixed the error and understood the issue.

As noted, it is a very basic 'C' programming issue - if you're still not clear on such basics, you are going to struggle with advanced stuff like BLE.

Have you studied the documentation?

You haven't said what chip you're using, or what SoftDevice you're using.

For S132 v6.1.0, the documentation is here:

https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s132.api.v6.1.0/group___n_r_f___s_o_c___f_u_n_c_t_i_o_n_s.html?cp=2_3_1_1_0_2_7_2

You will also need to study the chip documentation.

Have you looked at SDK examples?

It tells you what to declare!

You need to declare the thing which it told you was un-declared!

yes i know that meaning , what to declare ?

The 'C' programming language requires that everything must be declared before it is used.

This is basic 'C' - nothing specific to Nordic.

So, when the error says that something is un-declared - the solution is to declare it.

In the code you posted, there clearly is no declaration of the variable 'error_code'.

How to properly post source code:

RE: regarding the sleep mode

ps_anu — Sat, 10 Nov 2018 09:22:50 GMT

err_code undeclared (first use in this function)

So what error, exactly, does it show?
