sd_ble_gap_adv_start INVALID_PARAM

[q]

HI

sd_ble_gap_adv_start() is returning INVALID_PARAM when it's being calling in ble_advertising.c I have read through the documentation and I don't see anything incorrect. Furthermore, both arguments (adv_params and m_conn_cfg_tag) are identical to the arguments in a second project that does not return this error, so I know these parameters will work in some situations.

Here is adv_params:

{
  type = 0 '\000', 
  p_peer_addr = 0x0, 
  fp = 0 '\000', 
  interval = 40, 
  timeout = 30, 
  channel_mask = {
    ch_37_off = 0 '\000', 
    ch_38_off = 0 '\000', 
    ch_39_off = 0 '\000'
  }

Here is m_conn_cfg_tag:

$4 = 0 '\000'

Granted, these are two different programs (one has a custom service, the other is just the ble_app_cts_c example provided by Nordic), but I don't see how these other variables are related here.

Have you called ble_advdata_set() at all? Through ble_advertising_init() for example?
