ADD: 'lf t55xx deviceconfig' - command that allows for setting t55xx timings via the client. If run on a RDV40, it also saves the config to flashmemory. This gives you option to have custom timings for your custom antenna in order for your RDV40 to work optimal against a t55xx tag and with your custom antenna. (@iceman)
