getModuleInfo() fails for UBX-M10050-KB

[amnn314]

Subject of the issue

I found that getModuleInfo() returns false for my UBX-M10050-KB device. I have also found out that it happened because the payload did't contain 'MOD=' substring.

Here's the debug output I get, showing that there's no such substring, while FWVER and PROTVER are present:

Sending: CLS:MON ID:0x4 Len: 0x0 Payload:

I decoded it using the following Python one-liner:

>>> s = "46 57 56 45 52 3D 53 50 47 20 35 2E 31 30 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 50 52 4F 54 56 45 52 3D 33 34 2E 31 30 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 47 50 53 3B 47 4C 4F 3B 47 41 4C 3B 42 44 53 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 53 42 41 53 3B 51 5A 53 53 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0"
>>> "".join([chr(int(x, 16)) for x in s.split(' ')])

Expected result

Probably, DevUBLOXGNSS::getModuleInfo() could be fixed by not expecting all three items to be present.

Hi @amnn314 ,

Thank you for reporting this.

I was worried initially that you might have a cloned part. But, looking at the M10 SPG 5.10 Interface Description, it says that the MOD is only reported if available. I guess the UBX-M10050-KB chip does not report MOD.

I will correct this in the next few minutes.

Best wishes,
Paul
