    try to define parent id on the far node so that it always tries to connect via the repeater and see what happens

    Does this affect messages sent from the gateway to the node, too? I found nothing in the documentation about this.

      it affects the node that always uses the repeater and doesn't try to reach for the gateway directly.
      Use
      #DEFINE MY_PARENT_NODE_ID
      and add the ID of the repeater

        This has improved the overall latency for my node much, thanks.

        Anyway the serial gateway still seems a little buggy regarding the handling of broken messages, right?

            It should not restart.

              Ok, then it must be something else. Don't you have a regular Uno to try?

                The restarts seem to have stopped after setting a static parent. But the gateway should never restart because of some failed transmission imho.

                  agreed but when communications are not optimal bugs can come out.
                  Maybe @Yveaux @hek can add something?

                    Ok, now I can reproduce another bug that causes the serial gateway to restart:

                    2017-04-26 11:09:51.760 MySensors: Node: 14, Sketch Name: Molgan
                    2017-04-26 11:09:51.761 MySensors: Node: 14, Sketch Version: 1.0
                    2017-04-26 11:09:51.780 (MySensorsGw1) Lighting 2 (Security Sensor)
                    2017-04-26 11:09:51.928 MySensors: Gateway Ready...
                    2017-04-26 11:09:52.004 MySensors: Gateway Version: 2.1.1
                    

                    I have built several nodes based on the Ikea Molgan hack

                    I am using the included sketch without modifications.

                    Every time one of these nodes starts up, the gateway restarts. Without a starting Molgan node I did not see a single gateway restart for 24 hours.

                    @Yveaux @hek guys, can you please have a look?

                      @Jan-Gatzke There's nothing special about the Molgan sketch, so I seriously doubt the Molgan causing a gateway restart.
                      To be able to really help, we'll need more info:

                      • What radio are you using?
                      • Are you also using MySensors 2.1.1 to build your sensors?
                      • You state you're using a "dedicated voltage regulator". For what? What do you use as power supply?
                      • Foto's of your setup; it has helped others in the past...

                      Initially you reported restarting issues when the gateway tried to sent to nodes which were offline. For an nRF24 this causes the radio to excessive retry sending each message, placing a burden on the power supply. My first guess would be you have a power supply issue on the gateway.

                      Another thing you could try is running your gateway on a 16Mhz ATMega. In general the gateway is the part in your network that needs to process the most data, and therefore would require a 'powerful' processor.

                        • Radio is nrf24l01. The version with antenna and pa + lna . http://www.ebay.de/itm/272260489477?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT .I have wrapped it in aluminum foil which improved the communications much. MY_RF24_PA_LEVEL is set to RF24_PA_HIGH.
                        • Yes, most of my nodes including the molgans are also 2.1.1. Some other nodes are still 1.8.
                        • I am using Rev 7 of this board: https://www.openhardware.io/view/4/EasyNewbie-PCB-for-MySensors . I have connected it to the 5V Line of my Raspberry Pi. Power Supply is good, the rpi runs fine and stable. On the board there is a 3.3V regulator + the recommended capacitors. I also have an additional capacitor (47 uF) soldered directly to the nrf.

                          @Jan-Gatzke Perform following tests (in this order):

                          • Test with a regular nRF24L01, non-amplified
                          • Power from a separate 5V power supply
                          • I assume you're using the suggested LE33ACZ? It can only supply 100mA (if you get the original ones, not China clones) and the amplified nRF24 is said to draw over 100mA. You wouldn't be the first having issues (see here). Try powering from a separate 3V3 power supply, bypassing the regulator on the Easy/newbie PCB.

                          Do you see a difference between 1.8 and 2.1.1 Molgans?

                            oops, missed this limitation of the LE33. I will replace it by an ASM1117 and test again. Thx.

                                @Yveaux I really don't know whether this is a genuine chip. But I can still reproduce the problem after replacing the LE33. Tested with a non amplified nrf24, too. Same problem.

                                I have restarted two other nodes with an older version of mysensors (2.0 or 1.8). The gateway did not restart.

                                  @Jan-Gatzke so it doesn't reproduce then? Or only with 2.1.1?

                                    Correct. I have tested this with some other nodes. This seems only a problem with the molgan nodes. Even other nodes with 2.1.1 work without problems. Differences I see with the Molgans is the use of the internal oscillator and the use of the smd version of the nrf.

                                      @Jan-Gatzke well, my networks are all at 2.1.1 with Molgans. No issues whatsoever...

                                        Wie probably have the same problems with the smd nrf24 that we have with the regular ones, too. There is no big capacitor in the circuit of the molgan hack pcb. Perhaps this the cause of the problems. I will try to add one.

                                        Edit: Tried it with an additional 10 uF capacitor. That changed nothing.

                                          @Jan-Gatzke of course that doesn't help. The batteries have sufficient power to accommodate for the required power when sending.
                                          That's why I never add buffer capacitors to battery powered nodes.
