ble_peripheral/ble_app_beacon modification, error 0x12

[Erlend]

Using Segger Embedded Studio 310i in Linux and SDK12.2.0, I imported the Beacon example project (ble_peripheral/ble_app_beacon) from Keil. Right now I'm trying to make it advertise rather than act as a beacon. I removed what I thought to be unnecessary for this. Here is main.c now: bpaste.net/.../e839e61fa3ea

All the declarations of a variable a are just so that I can set a breakpoint. My problem is that there is no advertising and the LED doesn't blink. When debugging, it clearly crashes in advertising_start. In the breakpoint at line 101, I see that I have err_code = 0x12 = 18:

#define  NRF_ERROR_CONN_COUNT   (NRF_ERROR_BASE_NUM + 18)
  Maximum connection count exceeded. 

I don't understand why I get this error, even before it starts advertising.

I also tried to set PERIPHERAL_LINK_COUNT and CENTRAL_LINK_COUNT both to 1. Is a link a connection? - Then the error does make sense. However, it then crashes at the call to softdevice_enable_get_default_config, it seems. In the comments (line 33 and 34), it says that "When changing this number remember to adjust the RAM settings". But I'm not sure what is meant by that.

Hi,

You are doing BLE_GAP_ADV_TYPE_ADV_IND advertising (Connectable undirected), you therefore need to set PERIPHERAL_LINK_COUNT 1, or else you will get the NRF_ERROR_CONN_COUNT error. CENTRAL_LINK_COUNT should be 0. But as Roger Clark recommend, the beacon example does not show you how to set up a connection to a central, and you will save yourself from a lot of work if you start from scratch with e.g. ble_app_uart or ble_app_template example project. (Example that is actually set-up to act as a peripheral with a connection to a central.).
