Hi Members, *(Its my 3rd email and receive no response, Please give me help)* I am new in contiki. For many days i am trying to run experiments by using unicast sender and receiver examples and calculating RSSI Values. The problem is that 1) If *Receiver* mote start first and *Sender* mote later then no connection establish between motes. 2) If i start S*ender *first and then start receiver then link between motes establish but after some time motes disconnected and unable to *reconnect *if both motes reset many times. Sending *Packet interval is 1 packet per Second*. My target is to run experiments for *24 hours* without break. The same problem is occurring in *Cooja Simulation*. When both unicast-sender & Unicast-receiver motes are in range of each other they communicate but when i drag one mote away from the range of other mote after sometime when i drag back in the range of other mote then no communication is displayed No re connection establish. Radio traffic is shown but displays nothing. *Please help me i am stuck with it*. Is it RPL issue or something other. Thanks in Advance. *Best Regards:Sajid Hassan* |

Hi Sajid, I tried to replicate your problems, but it seems to work. I tried with Z1 motes. I tried both the situations and they worked.

Dear Pranav, Thanks for quick reply. On simulation put one mote out of the range of others one for a long time then drag back it will not connect. i do all the possible changes and checks. i test it with Release 2.7, 3.0 and even with 3.1 i received packets upto 55000. sometime in start it does't connect. when i make login in terminal sometime it displays as MSP430 Bootstrap Loader Version: 1.39-goodfet-8 Use -h for help Use --fromweb to upgrade a GoodFET. Reset device ... Done using saved target 'z1' fatal: Not a git repository: '../../../.git' ../../../tools/sky/serialdump-linux -b115200 /dev/ttyUSB15 connecting to /dev/ttyUSB15 (115200) [OK] no output shown after that message. The other thing is that i am using at receiver side* NETSTACK_MAC.off(1)* on simulation it indicate radio always on. when i use this line of code at unicast sender side on simulation both radios showing on but no no packet exchange just "Service not found" is displays from sender side. i am using contiki through VMware. what you suggestions to get rid of this problem. Looking forward for your kind response. Many Many Thanks in Advance. *Best Regards:Sajid Hassan* *Information Technology University (ITU), Lahore* On Thu, Apr 27, 2017 at 1:38 PM, Pranav Padalkar < pra...@es...> wrote: > Hi Sajid, > > > > I tried to replicate your problems, but it seems to work.
