    Yesterday I have successfully installed the ESP8266 module and it works fine, but the Vera3 show something strange now.

    @tjay4x4 Seems like to be an issue again when going from 8-bit to 32-bit architecture.
    Can you connect the ESP to your PC and capture the serial output when connecting to your lights and controlling them?

                  Yesterday I switched gateway hardware from serial gateway based on arduino pro mini 3.3V and nrf24l01+ (connected directly to uart port of my mikrotik router) to esp8266 nodemcu and nrf24l01+ (exactly as at this page: http://www.mysensors.org/build/esp8266_gateway, using GatewayESP8266 sketch from 1.6 branch, revision https://github.com/mysensors/Arduino/tree/1035f84a431a8f591d31100c3e73e99a8245e345).

                  I have 4 nodes with ~27 sensors total, half of sensors sending data every 10 seconds, another sensors send data only if environment changed.

                  After switching to esp8266 my gateway started loosing packets (messages) from my sensor nodes:
                  mysensors_esp8266.png
                  Left side of graphs is esp8266, right side is old pro mini serial gateway, sensors sending data every 10 seconds. Distance between gateways is about 5-10 centimeters. Both nrf24l01+ boards oriented in the same direction.

                  nrf24l01+ board isn't changed at all (I'm using old board from pro mini serial gateway).

                  Also, I have tried different nrf24l01+ boards (different PCBs and different chip revisions, but seems like all of them are fake china chips). I have tried soldering 220 uF electrolytic and 0.1 uF ceramic capacitors directly to nrf24l01+ power pins. But nothing changed. Esp8266 gateway is losing messages.

                  Switching back to pro mini serial gateway is completely solves issue (as shown in graph above).

                  What else can I try to fix this? Could it be interference between wifi chip and nrf24? Or, maybe, this is software problem? Maybe non-interrupt driven polling of nrf24l01 causes loosing messages coming too often?

                    Interesting graph... But I have no immediate answer to you.

                      @hek graphs are drawn by Zabbix. My own Perl script connects directly to gateway, reads sensor data and sends this data directly to Zabbix.

                      Also, I have tried to write raw data from gateway directly to file and execute "tail -f logfile.txt | grep sensor-specific-id". With old pro mini gateway data from sensor comes every 10 seconds. From esp8266 gateway sensor data comes very irregular.

                      Also, every send() call in all my nodes followed by wait(25) call to reduce possible power issues and interference issues.

                      UPDATE: I have recompiled esp8266-gateway sketch with debugging enabled, but I get the same results with loosing messages then I connecting directly to uart port of esp8266 uart-usb converter.

                        @robosensor What strikes me is the fact that most of the time not all sensor values seem to disappear at the same time. A failing WiFi connection would be the most likely cause when all dis/reappear at the same time (like at 13:44 and 13:22).
                        However, most of the time at least one sensor seems to report its values correctly. IMO This rules out the radio.
                        Is there anything interesting in the serial logs?

                          @Yveaux thank you for your reply. It is not failing wifi connection, as the same problem exists then I using serial connection to esp8266 (via on-board usb-uart converter on nodemcu board).

                          Nothing interesting in the serial logs (with debug mode enabled), just random absence of sensor data. Seems like I should connect sensor node to collect debug logs from node side.

                          Also speed is changed - much faster CPU (80 MHz vs 8 MHz) and much faster connection (wifi vs uart 9600 bps). Maybe this affects.

                            Seems like problem with loosing messages is gateway firmware related.

                            Then I connect two controllers (my own perl script and MYSController 0.1.2.282) to esp8266 gateway (#define MY_GATEWAY_MAX_CLIENTS 2), both controllers receiving exactly the same data from gateway, but messages lost even more.

                            mysensors_esp8266_two_controllers.png

                            1 on graphs = one controller connected
                            2 on graphs = two controllers connected.

                            I'm not familiar with esp8266 network programming, but could it be that firmware looses incoming packets from nrf24l01+ due to blocking call to wifi-related network functions? Seems like during sending data to wifi network firmware does not have time to pick up all incoming packets from nrf24l01+ chip.

                              I think I found problem. As I said before, seems like WiFi's clients[i].write() call blocks thread for a very long time.

                              I added logging of write() time:

                              		// Send message to connected clients
                              		#if defined(MY_GATEWAY_ESP8266)
                              			unsigned long start_time = hwMillis();
                              			for (uint8_t i = 0; i < ARRAY_SIZE(clients); i++)
                              			{
                              				if (clients[i] && clients[i].connected())
                              				{
                              					clients[i].write((uint8_t*)_ethernetMsg, strlen(_ethernetMsg));
                              				}
                              			}
                              			debug(PSTR("WiFi transaction time: %u ms\n"), hwMillis() - start_time);
                              		#else
                              			_ethernetServer.write(_ethernetMsg);
                              		#endif
                              

                              And got following results:

                              Seems like many packets coming to NRF24L01+ in this time interval (140-200 milliseconds) and this causes NRF buffer overflow and packet loss.

                                  @hek Yeah, but is this significantly longer than for a wired connection?
                                  Only real solution would be to switch to interrupt based message handling for the MySensors network (hopefully the ESP stack can handle this...)
                                  @robosensor Are these long delays (only) caused by the fact that this is a long distance connection?
                                  How is your mileage for a server on e.g. the same lan?

                                    Exactly same problem here with RFM69W Radio. With 2 clients, i loose more packets. Both controller and ESP are on the same LAN. No probelm with Serial Gateway on Jeelink v3.

                                      @Yveaux seems like delays caused by low-level network/tcp code or settings of receiving side (maybe something as TCP ACK packet delays or Nagle algorithm or something like this).

                                      ESP8266 connected directly to Mikrotik RB2011 router.

                                      Then I connect from external server (ping to server is about 55 milliseconds, FreeBSD 9.3, Perl), delays about 140 milliseconds.
                                      Then I connect from windows-based computer, connected directly to router, delays about 200 milliseconds (both windows telnet and PuTTy).
                                      For 2 parallel above connections delays about 350 milliseconds.

                                      Then I connect from router's internal telnet client, delays about 1-2 milliseconds
                                      Then I connect from android-based phone (phone connected to router via wifi, using ConnectBot software), delays vary from 3-5 milliseconds (mostly) to 100-150 milliseconds (less frequently).

                                      Seems like interrupts for nrf24 is the only solution. Seems like esp8266 gateway with such delays is completely unusable with high packet rates. With ~150 milliseconds delays no more than 6 messages/second packet rate allowed.

                                      Just to reference: I'm using Arduino 1.6.5 with esp8266 libraries version 2.0.0 installed.

                                        @robosensor @Fabien Please understand that this issue is not related to ESP8266. I expect delays to be nearly identical when using the Ethernet gateway (wired ethernet) and ATMega microcontroller. Of course the serial gateway will not suffer from these delays as it doesn't use ethernet as transport medium -- it is a direct connection.
                                        Switching to interrupt-based message handling for the MySensorts stack is not a simple task. It will require locking and buffering, and footprint of the library (especially RAM) will increase.
                                        Furthermore I don't know how the ESP's network stack handles interrupts during ethernet processing. Worst case it will just block interrupts or run from a higher-priority interrupt than the nRF and all efforts of making the MySensors library interrupt based will be in vain.
                                        I personally would try to reduce the latency in your server connection by choosing a server nearby or by buffering your traffic by a server in your LAN. MQTT for example can easily be buffered by a local broker which then uses the slow connection to sync with another server.
                                        Another option is switching to a serial gateway, but again you need a local server inbetween.
                                        A simple Raspberry Pi or so could act as a server for these scenarios.

                                        Another option would be to implement a retry mechanism on your sensors. If the gateway does not confirm reception of your message, then resend it.

                                          @Yveaux I completely agree with you. Rewriting gateway code to support interrupts is not very easy task and it is not clear what problems you will encounter. Furthermore, rewriting will not solve the problem of delays, this only can solve packet loss problem.

                                          Just tried to connect from RPi 2 (connected using WiFi directly to router), average delay is 2-5 milliseconds, sometimes 5-10 ms. Seems like this is good temporary solution.
