Bluetooth promiscuity - mergBLE confusion
If I execute `mergBLEScanForPeripheralsWithServices` with no parameters, I then get a shed-load of `mergBLEDidDiscoverPeripheral` messages, as expected (and as warned by the documentation for the service UUIDs parameter: If empty all discovered peripherals are returned regardless of their supported services (not recommended). One of the many peripherals that `mergBLEDidDiscoverPeripheral` reports has the service I'm expecting. If I specify this service UUID in `mergBLEScanForPeripheralsWithServices`, I get... exactly the same result as before, i.e. all the peripherals in range are discovered, regardless of the fact that only one is advertising the service. I'm also monitoring the `mergBLEPeripheralDidDiscoverServices` message; but this is never received. Another indication that I may not fully understand what I'm doing: I notice that of all the peripherals reported via `mergBLEDidDiscoverPeripheral`, only one includes any service info - the one which is actually a phone running another LiveCode stack which has used `mergBLECreateService`. While it is gratifying to find this one, it's surprising to me that none of the large cloud of other BLE devices that the scan is picking up advertise any services. What am I doing wrong?

Re: mergBLE usage
Actually... I didn't make that association... so thanks for your help in my previous exploits in mergBLE ... *AND*, of course (as you probably guessed), your offering this time was spot on!.. I'm still getting a handle on how LC handles things like background processing. I'm used to having explicit commands to send code off to run in the background. So the "timer" code runs in the "background" while the BLE commands and functions search for a connection. Cool! I'll get my head wrapped around this eventually... As to "dr_mumps", those are my initials "dr" and the MUMPS environment (used extensively in the VA hospitals lab systems) is my true expertise Cheers and thanks again!

Re: mergBLE usage
Ah... I didn't connect the "Doug" aka dr_mumps with your full name. (And you can probably guess that I'm milbybw). That's what I was saying, you need to write your own timeout. local sTimeoutCounter on openCard -- do your other stuff put 20 into sTimeoutCounter send "timeoutCheck" to me in 100 milliseconds end openCard on timeoutCheck -- using "-1" as the signal that we have found a device if sTimeoutCounter = -1 then exit timeoutCheck end if subtract 1 from sTimeoutCounter if sTimeoutCounter = 0 then answer "Did not find anything in time" -- call your timeout handler else send "timeoutCheck" to me in 100 milliseconds end if end timeoutCheck on mergBLEDidDiscoverPeripheral pPeripheral, pName, pRSSI -- in the code where you identify that you have found your particular device, add this put -1 into sTimeoutCounter end mergBLEDidDiscoverPeripheral ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
Re: mergBLE usage
I’m guessing you have a card that when you open it will initiate a look for available connections. You have the appropriate handlers in place that work if one is found. Now you want the card to not wait forever though? If that is the case, there are a couple threads on the forum that may help: https://forums.livecode.com/viewtopic.php?f=75=30892 https://forums.livecode.com/viewtopic.php?f=66=30853 When you initialize the card, you need to start a process that checks for an active connection. If time runs out before a connection is made then call the exception routine. If a connection is made, cancel the check process. Here is an example from the other threads: https://forums.livecode.com/viewtopic.php?f=9=30862#p165981 (Not exact since in that case a device had already been discovered and it was waiting on a reply message.)

mergBLE usage
Monte... or anyone else brave enough to contribute :-) (no colored emoji, sorry) ... Is there a way to time out the attempted connection to a BLE device using the mergBLE functions. I can't seem to find a command which doesn't need a peripheral UUID ... like "mergBLEConnectPeripheral pPeripheral" ... which has a corresponding "fail" message: "mergBLEDidFailToConnectPeripheral pPeripheral, pError " ... or can I use this command/message combo in some way to look for a BLE device and if not present (or if NO BLE device is present / active), timeout and fail? I need my LC code to be able to detect whether a BLE device is present and if not "move on" ... right now, my modified code, taken from the example mergBLE script, just waits forever for a peripheral which may never appear.

Re: mergBLE?
The mac side could certainly be done with mergBLE. The iOS side would require a Call Directory Extension using CallKit and CoreBluetooth then add that into the LC app when building. I think you would be breaking new ground doing that though so it would be worthwhile discussing with LC Business Services. > On 9 Dec 2017, at 11:14 pm, Mats Åström via use-livecode > <use-livecode@lists.runrev.com> wrote: > > Hi all, > > for a client I would like to build an OSX app that would use the phone number > of an incoming call on an iPhone to present the documents associated with the > client calling. > > I then need to connect to the iPhone (maybe using mergBLE) and obtain the > phone number of an incoming call. > > Is this at all doable in LiveCode? > > /Mats > ___ > use-livecode mailing list > use-livecode@lists.runrev.com > Please visit this url to subscribe, unsubscribe and manage your subscription > preferences: > http://lists.runrev.com/mailman/listinfo/use-livecode ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
mergBLE?
Hi all, for a client I would like to build an OSX app that would use the phone number of an incoming call on an iPhone to present the documents associated with the client calling. I then need to connect to the iPhone (maybe using mergBLE) and obtain the phone number of an incoming call. Is this at all doable in LiveCode? /Mats ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
