android - How to connect pybluez RFCOMM server socket on Debian? -

-

i have these snippet in python pybluez framework:

from bluetooth import *  server_sock=bluetoothsocket( rfcomm ) server_sock.bind(("",port_any)) server_sock.listen(1)  port = server_sock.getsockname()[1]  uuid = "94f39d29-7d6d-437d-973b-fba39e49d4ee"  advertise_service( server_sock, "sampleserver",                    service_id = uuid                    # service_classes = [ uuid, serial_port_class ],                    # profiles = [ serial_port_profile ],                    # protocols = [ rfcomm_uuid ]                     )  print "waiting connection on rfcomm channel %d" % port  client_sock, client_info = server_sock.accept() print "accepted connection ", client_info  try:     while true:         data = client_sock.recv(1024)         if len(data) == 0: break         print "received [%s]" % data except ioerror:     pass  print "disconnected"  client_sock.close() server_sock.close() print "all done"

and have other snippet in android connect pybluez rfcomm server socket:

private static final uuid my_uuid = uuid.fromstring("94f39d29-7d6d-437d-973b-fba39e49d4ee");  .... bluetoothdevice device = mbluetoothadapter.getremotedevice(myservermacaddress); .... bluetoothsocket tmp= device.createinsecurerfcommsockettoservicerecord(my_uuid);

my problem android device not connect pybluez socket. think way use connect wrong, , don't know how connect correctly or advertise server socket

i offered bounty, found solution myself. :) posted on answer may apply problem. on versions of debian (raspbian etc) , maybe others distros. server_sock.accept() default hang , never accept connection - paired device! i'm in cases convinced socket isn't open @ all. however, solution simple.

update /etc/bluetooth/main.conf file, add line or change existing looks this:

disableplugins = pnat

then restart bluetooth service:

sudo invoke –rc.d bluetooth restart

it may have been fixed.

good luck!

reference: rfcomm without pairing using pybluez on debian?

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
