Currently, the ble_ll_iso_big.c unconditionally uses the crypto functions. Thus the code won't compile with encryption support disabled (BLE_LL_CFG_FEAT_LE_ENCRYPTION unset).
For now, 23eec0a workaround has been merged that enables the encryption by default if BLE_LL_ISO_BROADCASTER is enabled.

My question is:

  1. Should there be a possibility for the user to build a controller without a encryption support and Broadcast ISO support, so that the user would be able to send and/or receive unencrypted broadcast only, or
  2. Should there be an restriction for BLE_LL_ISO_BROADCASTER with BLE_LL_CFG_FEAT_LE_ENCRYPTION dependency
