First of all thank you "bbousquet"

to try to write this type of program which is really missing for WM5, despite my results

:
Failure :
Connection well establised with the Mobile Phone: When "send" buttom is push, question on the phone:
Connect DUN service with "pda_name"?, answer yes.)
then "
Communication timeout", (once"SMS sent" but not sent), then "Failed to connect", then sometime trouble with the PDA. Must do a soft reset.
Mode used : both PDU and Text
PDA: axim x51v WM5 A01 (french)
Phone:
Samsung D600e, France, GSM
So, it seems I have (not always) the known issue of the BT socket not properly closed after a "Communication timeout " error, needing to often soft reset the PDA.
But I'm sure you will find solutions. I'm ready to make all the tests you want with my Samsung D600e.
Thanks again for your searchs:approve: .
