The device I am using is the Honeywell Dolphin 60s and I am connecting this to a bluetooth serial converter. I am able to pair the device with no problem and this creates two com ports, one for outbound communications (COM4) and one for inbound communications (COM0). I can successfully connect to COM4 and can easily send data to the bluetooth device from the Dolphin 60s using the sWrite command. However i cannot open COM0 and typically the project requires the ability to receive data from the serial port, not send it. I have tried the following sOpen commands with no success:- sOpen(0,1024,1024,100,TRUE) sOpen("COM0",1024,1024,100,TRUE) Neither of these commands will open COM0 on this device through Windev Mobile. If I change the commands to 4 or COM4 then both of these work for COM4. For sanity sake I have installed a third party application for opening com ports and this was able to open both COM0 and COM4 with no issues. Can anyone offer any guidance as to what I could be doing wrong or have any ideas for a workaround? Thank you for any assistance : ) Kindest Regards, Lee Shroder30WEBDEVen_UShttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/66202-windev-mobile-23-sopen-wm6/read.awpmoderateur@pcsoft.fr (El moderador)webmaster@pcsoft.fr (El webmaster)guestpcsoft.us.windevhttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/66202-windev-mobile-23-sopen-wm6-66240/read.awp19 Jul 2018 13:41:00 ZIt probably wont make a diference, but make sure that you are using a variable declared as an int on 1 to pass the zero value …https://forum.pcsoft.fr/es-ES/pcsoft.us.windev/66202-windev-mobile-23-sopen-wm6-66240/read.awphttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/66202-windev-mobile-23-sopen-wm6-66240/read.awpWindev Mobile 23 sOpen WM6.5guestpcsoft.us.windevhttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/66202-windev-mobile-23-sopen-wm6-66215/read.awp18 Jul 2018 19:09:00 ZHi Fabrice, Thank you for the concept but unfortunately still no success.
