      Hi,

      for the power, if It isn’t too big a panel like this


      AliExpress.com Product – 10Pcs/Lot DIY Toy 5V 30mA 53X30mm Micro Mini Small Power Solar Cells Panel Wholesale DIY Sun Panel

      without a resin they are flexible and can cover all the pakage, probably can be sufficient to recharge the device quite fast.

      There are some type of battery for bracelet or similar very small but about 50mha


      AliExpress.com Product – Liter energy battery Good Qulity 3.7v polymer lithium battery 50mah 501012 is suitable for I7 bluetooth headset MP3 MP4

      The drone battery can be quite small,


      AliExpress.com Product – 051230 501230 150mah BT150 Bluetooth Headset 3.7V lithium polymer battery

       

      For LoRa I finish first release of Ebyte E22 LoRa devices that have a repeater function, and If we must track a small area like 60km with some device as repeater put in the area can cover with RF the transmission.

      Ebyte LoRa E22 device repeater relay function ultra long distance

       

      But We need more detail to do an evaluation.

        Hi Joaquin,

        to start you can try with

        SIM900A

        BN220

        For microcontroller the smt32 have a good power and consume, but you can check of the are library for module.

          I’m happy you have find the solution.. If you need more help or you have some idea to add to the library write on Forum without problem.

            Hi JoaquinC,

            I think It’s better to limit the spec to only what you really need, but for fisrt we must select some GPS small like one for drone, like this

            GPS Module compass

            GSM Module

            or a radio with 8km range like

            LoRa E32 device for Arduino, esp32 or esp8266: specs and basic usage – Part 1

            Thank It’s important to select a rechargeable battery powerfull and light, this is a choiche that you can find when you have a base to test, but you can select a big 18650 with 3400mha

            3400mha 18650 battery

            or a 523450 fot about 1000mha

            1000mha 503450 Battery

            If you must have less weight you can choiche a drone battery with low capacity but very small

            250mAh 402035 battery

            Chan you can use a system like this to recharge

            Emergency power bank homemade

             

            I think the microcontroller is not so important because for a lot of time It’s become in sleep mode, some SMT series have a very low power consmuption, other like PIC one or ATMega.

            I think you can use also a WeMos D1, but when you are going to create a board you must use the IC not the board.

            WeMos D1 mini (esp8266), pinout, specs and IDE configuration – Part 1

             

            But you must specify more information about you want to do, like

            • form factor
            • weight
            • distance
            • frequences

            and all other spec you want raised.

              Hehehehehhe… Keep calmp….

              The sketch I send you is fully working and tested (I do it with an esp32 devkit v1 and WeMos, I try It with an Arduino also and 2 e32 433, that you can see on photo).

              Pay attention I comment the first 2 define anche change power to adapt to my devices.

              We can go by step, send me your connection schema, I’m going to do the same connection, and tell me what kind of pull-up resistor you have used.

              than if It’s ok I ask you to resend all the code.

              Hold on, we’ll find the problem: P.

                Hi Alejandro,

                I check your code, and there are some issue, first is the type of communication setted to TRANSPARENT

                But I have found an issue/problem in the library and I change It, two constructor of esp32 is ambiguous, so I change the disposition of the constructor that have specifies setting of HardwareSerial,

                To undestand

                LoRa_E32(HardwareSerial* serial, byte txE32pin, byte rxE32pin, byte auxPin, byte m0Pin, byte m1Pin, UART_BPS_RATE bpsRate = UART_BPS_RATE_9600, uint32_t serialConfig = SERIAL_8N1);

                now is

                LoRa_E32(byte txE32pin, byte rxE32pin, HardwareSerial* serial, byte auxPin, byte m0Pin, byte m1Pin, UART_BPS_RATE bpsRate = UART_BPS_RATE_9600, uint32_t serialConfig = SERIAL_8N1);

                but in your case the code become more simpliest with the direct usage of Serial2

                Here the sending code for esp32

                
                #include "Arduino.h"
                //#define E32_TTL_1W

                #include "LoRa_E32.h"
                
                // Not needed Serial2 have already this pins
                //#define RX 16

                  Hi Alexander,

                  I’m happy that now e32 working correctly, but I don’t know dragino and I’m not able to help in that comparison.

                    Thanks Alexander,

                    Do you have the shield for WeMos, you get the error with that??

                    With 868 version sometime there Is a problem with the pull up resistor, but with Arduino.

                    Of you use the shield you can refer to this article LoRa E32 device for Arduino, esp32 or esp8266: WOR (wake on radio) microcontroller and new WeMos D1 mini shield – Part 7 but the configuration is

                    LoRa_E32 e32ttl(D3, D4, D5, D7, D6);

                     

                    And yes, I must update the schema ;).

                    If you give me more information we try to debug your problem.

                      Hi Mario,

                      I put a piece of my Inverter monitor where I send a set of value via mail when there is a problem

                      EMailSender::EMailMessage message;
                      const String sub = F("Inverter error!"); // Here the subject
                      message.subject = sub;

                      const String mp = F("Error on inverter centraline");
                      const String ft = (fixedTime)?F("OK"):F("NO");
                      const String sd = (sdStarted)?F("OK"):F("NO");
                      const String wc = (wifiConnected)?F("OK"):F("NO");
                      const String sf = (isFileSaveOK)?F("OK"):F("NO");

                      // Here the message in html format
                      message.message = mp+
                      F("<br>Time fixed: ")+ft+
                      F("<br>SD Initialized: ")+sd+
                      F("<br>Wifi Connecter :P: ")+wc+
                      F("<br>Saving file ok: ")+sf+
                      F("<br>Wrong saving attempts: ")+sdWrongReadNumber;

                      EMailSender::Response resp = emailSend.send(emailToSend, message);

                      The result is

                      Error on inverter centraline
                      Time fixed: OK
                      SD Initialized: OK
                      Wifi Connecter :P: OK
                      Saving file ok: NO
                      Wrong saving attempts: 10

                        The sensor is a DHT12, and the value -127 isn’t present.

                        Can you put an example of your idea.

                        Thanks Renzo

                            Hi Rossic, It’s strange, do you have set the pull-up resistor?

                              Hi Joergen,

                              I think the relevant error is

                              501 5.5.2 <mischianti:>: Helo command rejected: Invalid name

                              probably you aren’t attached to the Sunrise contract line, and you can use SMTP only with Sunrise line.

                              For example, if you have a Sunrise cellular line and you try to access SMTP via your home line the provider reject the request.

                              As test (if you don’t use a mail client) you can try to configure a client like Outlook to send email from the same line.

                               

                              Tell me if is this the problem.

                              Bye Renzo

                                Hi cglkr97,

                                as you can see in the file at line 228 I add e32ttl.setMode(MODE_1_WAKE_UP); than I use simple Int value to set ADDH, ADDL and CHAN (I print the HEX value to check the channel).

                                I don’t have problem to use decimal value instead HEX.

                                I try to send a string value without problem, If you use ArduinoJSON pay attention the string generated isn’t clean value check this http://mischianti.org/forums/topic/how-to-send-message-use-json-format/

                                But if you want use a String value remember that you have only 59Byte to send message and binary data like structure is good optimized.

                                Bye Renzo

                                  Hi,

                                  I do some change (set WAKE UP mode to sent do the receiver) and I set channel to 4 (but I test It with 17 also with send 23 that in HEX is 17) and works correctly the first handshake.

                                  I used 2 arduino UNO (with my shield) but no overflow.
