Thank you for reporting this, we will check it and fix it during next update. There is already unofficial v1.9.0c with some improvements, but I'll need to check if it's already fixed or not.

UTCOMP Android update v0-1.6 will be soon available for beta testers (you can register for early access here https://play.google.com/apps/testing/com.reveltronics.utcomp ) - app is during verification by Google Play. We would like to continue developing UTCOMP Android app, but from few months we wer...

UKP Android doczekała się nowej aktualizacji v0-1.6, w ciągu kilku dni (jest w trakcie sprawdzania przez google) będzie dostępna dla betatesterów (tutaj można się zarejestrować https://play.google.com/apps/testing/com.reveltronics.utcomp ) i niedługo później oficjalnie. Chcielibyśmy dalej rozwijać a...

REVELPROG-IS application does not have access to memory database file or file is missing. Please check if file device_list is available in location "%appdata%/REVELPROG-IS". If file is missing - please reinstall the software with admin rights. If file is there - something is blocking acces...

I think that issue is still with connection or faulty chip. I just checked DS2430A in ZIF socket and it's working fine, read/write is working.
This is how I connected it:

Are you programming in external circuit or directly in programmer? You do not have to use any resistors in series for VCC. This chip is easy , only 3 wires are required for read/write: data (pin5), ground (pin4) and vcc (pin8) - that's all and it has to work. Please send me pictures of your connecti...

Please use calibration data for above sensor: R25 = 10500 Beta = 3536 It should work above >40C. Below 40C readings may be inaccurate because I can not see scaling table below this range. If sesor "A" connected to AdcVcc1 is working fine and the same type of sensor "B" connector ...

Are these sensors connected only to UTCOMP or are they connected to external ECU and UTCOMP in parallel ? Please tell me how did you connected them and share me resistance table of these sensors.

Może mieć znaczenie, np. jak pamięć pracuje na niższym napięciu, ale inne kompatybilne zamienniki też będą działać, np. 24LC16

Please send me a photo from bottom side of board and soldered connector, I'll take a look (there are 2 jumpers with protocol configuration)
