Så, nu har jag fått igång den. Mailade med ps idag. Dom va riktigt snabba med svar och lösningar. Visade sej att firmware va raderad på enheten, så efter några försök fick jag igång den. Kan väll säga att den här doseringspumpen inte är något för den som inte kan datorer. Nu ska jag bara få den att dosera rätt. Slänger upp mailet från ps. Kanske hjälper det någon. It looks that You have deleted firmware from doser. You will have to make firmware upgrade with reset procedure please fallow this instruction: > Firstly - DON'T USE internal bluetooth modules - they are weak - and not fully SPP compatible. > Be close to lamp also - to protect against CRC errors.. > 1.Run Pacific Sun application and in Connection tab set proper com port and WITHOUT PRESSING connect button go to service tab > and open dialog window(by pushing Firmware upgrade button) for bin file - but not confirm it yet.. > Please look at back of doser there You have 3 position switch (this one which is used for LCD backlight turn on and off). On down position is reset mode. > Now You must apply proper firmware file in Pacific Sun software window and turn switch to down position (reset) for a while(short moment) AFTER you will confirm on your application which firmware file you want to open and then set it in up position back - LCD backlight will light. > This will generate reset command for computer - without unpowering > main BT module - so communication between PC and BT module in doser will bestill alive. > You will see short blink on LCD - and doser start uploading firmware again.. > When upload will be done please press default settings button. Please try few times because it's hard to do it in first time - You have only short time from apply firmware file to switch to reset position and back to normal position. Best regards Tomasz Laskowski
