bluecove problem

Hi all,

I am using BlueCove (http://bluecove.org/bluecove-emu/index.html) to simulate the bluetooth on my laptop and Eclipse 3.5 with Dsdp plugin for codeing the ME application. The emulator works well with my J2SE application (server); however, when running with the phone emulator (client), it gives this errors



this is my command to run it

( i am using linux)

and this is my MANIFEST in the PhoneSide.jar

From what i found on google, i think i have to add the permisson javax.microedition.io.Connector.bluetooth.client but not very sure about it coz I am not familiar with bluetooth programming. Can anyone help me, please?

"Invalid signature file digest"

It sounds like you either didn't sign the MIDlet or you made mods after it was signed. Probably not actually a bluetooth problem.

thank you for your reply. I think there 's something wrong with eclipseme and try to figure it out coz that bug only happens when i activated the jad file through the BlueCove emulator from command line but doesn't appear when i run it on eclipse. I also tried BlueCove with the mobility pack of netbean and it work perfectly.

well, bluetooth is not the suitable way for my application anymore due to the short distance for sending. SMS may be the next option that i should consider. After searching for a while, i see that there is no free service to support sms sending, even in this country where i study, all the carriers alreay stoped this kind of service.

The only way i can use now is trying to use service from yahoo, hotmail, or skype. Do they provide any API to support sms programming? Does anyone experience with this? There is a third party API (jYMSG) for yahoo chatting but unfortunately it doens't support sms

All you need to do to send SMS (for free) is send it as an email. Most phone services synthesize their SMS target addresses from the recipient's phone number and some mail domain they've set up for the purpose. Unfortunately, the exact details vary from service provider to service provider, so you have to know what carrier your recipient uses.

Also, of course, SMS is only "free" to the degree that the gateway email port is free. Recipients will still likely get billed for the messages.

Don't forget that anything sent via SMS has to fit into 140 characters of text!

I knew that an email can be sent to a phone as a sms. (for example, 1 year ago, i still can send an email to phone_no@sms.celcom.com.my and that email will be sent to the phone_no as a sms). However, these kinds of service dont exist in this country anymore. I also tried to send message from my laptop by using GSM modem, but that device is not suitable for my research . The only way that i can think now is using service from yahoo or skype

btw, thank you for your quick reply
