Weathershield failing? [solved]

[DrSproc]

Don't give up try a fresh install as suggested.

I installed the latest IDE (1. reinstalled all the libs, same outcome. Now I do get a notification that an update is available for SPIFlash but it points to https://github.com/Marzogh/SPIFlash, not https://github.com/LowPowerLab/SPIFlash?

But as stated before, it can't be the software, I have different weathershields that are working properly.

I performed some more tests:
[1] BAT:4.86v C:0.00 H:0.00 P:6420.70   [RSSI:-36][ACK-sent] <= this one has no weathershield
[2] BAT:1.59v C:0.00 H:0.00 P:6420.70   [RSSI:-38][ACK-sent] <= this one has the faulty weathershield
[3] BAT:4.86v C:21.35 H:37.00 P:30.12   [RSSI:-32][ACK-sent] <= this one has a properly working weathershield

ok Looks like you have a bricked shield...

I test all shields after assembly to ensure I can read the sensors etc. After that point a few things can happen obviously but it's hard to pinpoint the problem, not at least without looking at it.
If all-things-equal (software wise) you have a working one and one that's not working, then it could be something in hardware (soldering, zapped sensor?).
I can offer to look at it if you send it back and I can try to debug/fix it if possible.

It's kind of you but I probably made an error soldering it.
All the pins seem to give contact somewhere on the board except for A5/SCL, I can't find any connection to it?

For example A4/SDA seems to be connected to one of the pins on the BME280 chip and the bottom right pin on the socket where the Si7021 would be.

Based on the green lines on the back I'd expect that SCL should connect to the bottom left pin on the Si7021 socket?

A5 connects to the BME280, try to follow the trace and see where it stops having continuity.

[MPParsley]

So when I soldered it the first time I must have accidentally "cut" the trace near A5 (probably too high temperature), I fixed it now and the weathershields properly working.

Thanks for the information.
