How to move code out of main.c

[Ricco]

I am using multilink (version doesn't matter)

In main.c, certain variables, i.e., m_lbs_c,  are declared and used in, i.e., led_status_send_to_all.

        BLE_LBS_C_ARRAY_DEF(m_lbs_c, NRF_SDH_BLE_CENTRAL_LINK_COUNT); /**< LED button client instances. */

These are defined in ble_lbs_c.h

   static ble_lbs_c_t _name[_cnt]; \
   NRF_SDH_BLE_OBSERVERS(_name ## _obs, \
           BLE_LBS_C_BLE_OBSERVER_PRIO, \
            ble_lbs_c_on_ble_evt, &_name, _cnt)

I want to pull code out of main and put into other sub.c file for better organization,

for example, pull led_status_send_to_all into sub.c file, yet I must access m_lbs_c.

static ret_code_t led_status_send_to_all(uint8_t button_action)
{
ret_code_t err_code;

for (uint32_t i = 0; i< NRF_SDH_BLE_CENTRAL_LINK_COUNT; i++)
{
err_code = ble_lbs_led_status_send(&m_lbs_c[i], button_action);
if (err_code != NRF_SUCCESS &&
err_code != BLE_ERROR_INVALID_CONN_HANDLE &&
err_code != NRF_ERROR_INVALID_STATE)
{
return err_code;
}
}
return NRF_SUCCESS;
}

I do not know how to define an external definition of m_lbs_c  so that I can put led_status_send_to_all into sub.c?

I do not know what I have to #include in sub.c?

Can you help?

thanks,

Richard

These are basic 'C' programming questions - nothing specifically to do with Nordic.

BTW - how to properly post source code:

Thanks, I got it.

To gain access to glo_c, I put this in my function sub.c

#include "ble_glo_c.h"
extern ble_c_t m_glo_c[NRF_SDH_BLE_CENTRAL_LINK_COUNT];

Apparently not!

You didn't follow the instructions to post the source code.

The 'extern' declaration should be in the header file.
