I plugged the PAW supplied U-Blox 7 dongle into the u-Box development toolset (I have a GPS development toolset here, long story) and I could not set it to GLONASS at all, it would just revert back to GPS. However it was receiving EGNOS though.
Watching the config commands it receives and acknowledges them, but doesn't act on them. I tried to update the FW to uBlox7 1.01 from the v1.00 it says it has installed, it failed to detect the internal flash. So I tried to ask the chip for it's OTP uBlox security ID programmed as it leaves the factory, I get blank back, so I suspect it's a fake chipset in the dongle, not a surprise given the cost of them.
Although another U-Blox M8N receiver I have here is doing a sterling job of getting hold of GPS, GLONASS, and Gallieo with EGNOS support too.
