I have some LAP1242 which by mistake were bought for Mesh. I am trying to convert them to LWAPP so what I did first was to convert them to Stand Alone then to LWAPP but I cannot get the AP to join the WLC and sends several error logs.
I attached some logs taken from AP and WLC so that you can figure out what's going on.
I wonder if I have to remove anything from flash either on SA or LWAPP mode (I know that in some cases you have to delete privete-config in order to avoid the AP taken previous configurations). By the way I think I had never seen this c1240-k9w8-mx.124-25e.JA2 on an AP IOS before, I wonder if it has to do with the mesh thing.
