After the 0101 is sent to the si2147-A30 it will still execute commands but you will not get the answer back through the si2168. You just get ff. After moving the chip id readout from si2157_init to si2157_probe, scanning for stations works. So the si2147-A30 seems to react on commands. Regards, Andreas Kemnade
