由 纵饮孤独 提交于 2019-12-06 22:31:42
问题 I'm wondering if, with the G1, it's possible to force the network traffic to pass through the Wifi or through the Cell GSM network. I need to force an application to connect through the tower network to get some login information. Is this possible? Anyone have any ideas as to how this would be possible? I'm trying to accomplish this inside an app with the Android SDK (Sorry I wasn't more clear about that originally) 回答1: It turns out to be possible using the WifiManager object to disable and

Android - supress the native In Call Screen and replace with 3rd party?

由 馋奶兔 提交于 2019-12-06 12:07:50
问题 Currently creating a VOIP application for Android and I was wondering is there any possible way to supress the In Call Dialog when sending a call over GSM and use our own 3rd party In Call Dialog or screen instead? At the minute when we switch from our VOIP call and send it over GSM via the ACTION_CALL intent it does everything we want except it brings up the native In Call screen whereas we want our own In Call screen to display here. So I was wondering what kind of options we would have on

Is GSM data sending between 2 phones impossible?

由 萝らか妹 提交于 2019-12-06 07:21:44
Please tell me in detail why it is impossible to send the data between two phones over GSM? I can find almost no information about this problem. user1725145 There are 2 points here. Firstly, GSM is a mobile voice telephony system - plain GSM doesn't do data connections. GPRS and EDGE are add-ons to the GSM network that allow data to be sent. There are other kinds of wireless phone networks that also use a SIM and allow data to be sent (UMTS, LTE). Secondly, when you establish a data connection with a mobile phone and a phone network, you are establishing an IP connection between your phone

Terminating a voice call via AT Command

由 こ雲淡風輕ζ 提交于 2019-12-06 07:18:14
问题 Im working on a hobby project involving an Arduino and TC35 GSM Module, all is going well really but I am wondering is there an AT Command to terminate a voice call (ATD+phone number;) as I cannot seem to find one in any of the literature I've searched through. Thanks, Dave 回答1: I think the answer to your question is ATH0 from memory 回答2: While the "classic" command ATH (there is no need to give a numerical argument to ATH) is applicable for disconnecting calls, notice that it might be

Concatenated SMS extended symbols at segments border - what is correct split method?

由 喜夏-厌秋 提交于 2019-12-06 04:20:43
For concatenated SMS messages (in GSM encoding), if extended table symbol (one of these: }{[]|~^\€) is placed at the end of segment, what is correct way to split such message: Leave first byte of symbol (0b) at the end of segment and put second byte to the beginning of next one, and so fill all available bytes of UD (which seems logically correct) OR Move whole symbol bytes to the next segment and leave unused byte at the end? I didn't found any clarification neither in SMPP 3.4 specs or implementation guide nor in GSM 03.38 specs, so assume that method selection is up to content provider or

Getting CID, LAC and signal strength of all cell towers in range

由 ∥☆過路亽．° 提交于 2019-12-06 03:17:45
问题 Currently I am trilaterating my Android with the cells in my network. It is even more accurate than I thought it would be. But not as accurate as I want it to be. So I want to involve more towers than I get from getNeighboringCellInfo. I want to get the Cell ID and signal strength of every tower in range. Of every network operater. Is there a way to "ping" the towers, so they answer with cellID, Lac and signalstrength? Somehow this has to be possible. And can I scan the 2G and 3G (and 4G)
