Looking at the P1-Pinmap.xls reveals no PB14 and PB15 USB Data +/- exposed on any pads. Is that correct,and if so, i guess that means no DFU firmware upgrade possible, and further USB related ?
The http://www.cnblogs.com/shangdawei/p/3485122.html page related to WM-N-BM-14, says “RF Spec, MCU Spec and the deliverable are same as WM-N-BM-09” (P0), but if the USB is missing, i guess not… ?
Is the above correct ?, the P1 documentation is a little sparse until now…
btw looking forward til P1’s and photons starts shipping
