I am seeing exactly the same jump in SG with my four brews since building the iSpindel. Why I don't know, my temperature remains stable, I guess it just would not be noticed with a conventional hydrometer. The brew also generates a couple of degrees of heat, which I would not notice had it not been for the iSpindel.Pop in the spindle, get a low reading, then it jumps in SG. you can see from the attached image. When I Calibrate its spot on and water cal gives 23.4 deg for 1.000 SG @ 22 Deg C
Any Ideas ???
Adjust it for the 25 degree list at 20C, then use the sugar calibration method to get a polynomial fomulae accurately.A question about calibration? can i use a brew and get readings with a hydrometer for the polynominal formula?
If I understand correctly I need to resolder the 0 ohm resistor into the green position. In that case the ceramic antenna is not working anymore and have to buy an external antenna like in the attached picture? Only if the signal is not sufficient at the moment.The diode is generally removed to avoid issues with using the USB on the Wemos whilst having the iSpindel turned on and also powered via battery. This is the reason I suggested that it's not really needed as you can't really "accidentally" power the Wemos independently, given the rotation of the USB port (not facing up).
The antenna on the D1 Pro usually isn't as good as the normal D1 mini, unless you're using the IPX port with an antenna. Based on the orientation of your first photo, take a look at the top, mid-left. There is a small surface mount component with a 0 or 000 on it. You can follow the track out of the ceramic antenna and the IPX socket which has a pad with nothing on it.
I have the same problem, somebody solved this problem during flashing?Have not given up on this purple iSpindel. I had a similar problem with orange iSpindel but fixed it by re-flashing the firmware. Thought I would try the same again on purple.
Anyway, firmware will not flash to purple. NodeMcu sits in "waiting" mode waiting the iSpindel. Putty logs shows the iSpindel looping through what looks to be the startup scripts. The iSpindel appears on the network and just as quickly disappears. Tried reset button 3-4 times and no change.
Is there a way to wipe the iSpindel's current memory or rest the device and re-flash the firmware?
Gents and Ladies,I have the same problem, somebody solved this problem during flashing?
It does nothing after you push the flash button.
The logg shows:
Noteetect serial port changed.
Note:Auto MAP serial port.Port-->COM3
Note:Serial port connected.
Note:Begin find ESP8266.
the following message appears as a sequience during the 'flashing' but does not come to an end.

Tried multiple USB cables, similair for the software, latest release but also some of the versions that was shown in a youtube movie explaining how to flash.
Hope somebody can help me out.
