Arrived in good time. This is either an older chipset or the USB serial is not the best as for the first time in a year of buying and using these I had to change the flash frequency from 80 to 40Mhz.Uploading at 80 Mhz puts the chip into a permanent start restart state. True on 3 of 50 modules. I have not tried all otherwise all packets will be opened.
