Ciao Renzo,
prima di tutto ti volevo ringraziare per l’ottimo lavoro che hai fatto con queste librerie.
Ho collegato un E32 ad un arduino pro mini praticamente senza problemi grazie a te.
Sto riscontrando delle difficoltà invece cercando di collegare l’E32 ad un esp8266 (un nodeMCU che ho qui in casa).
per quanto riguarda il cablaggio mi sembra tutto apposto come da tua guida, ti posto una foto:
cablaggio
sto provando ad usare l’esempio della GetConfiguration ma credo di sbagliare qualcosa con le porte seriali.
quando provo a caricare lo sketch tramite arduino ide mi va in timeout cercando di collegarsi alla seriale.
Se scollego i pin 7 e 8 riesce caricare lo sketch.
Da quel (poco) che so la scheda ha sui pin 7 e 8 rx2 e tx2.
Dove sto sbagliando?
ti allego anche il codice.#include "Arduino.h" #include "LoRa_E32.h" //HardwareSerial Serial2(2); //LoRa_E32 e32ttl100(&Serial2); LoRa_E32 e32ttl100(D8,D7); // Arduino RX <-- e32 TX, Arduino TX --> e32 RX void printParameters(struct Configuration configuration); void printModuleInformation(struct ModuleInformation moduleInformation); void setup() { Serial.begin(9600); delay(500); // Startup all pins and UART e32ttl100.begin(); ResponseStructContainer c; c = e32ttl100.getConfiguration(); // It's important get configuration pointer before all other operation Configuration configuration = *(Configuration*) c.data; Serial.println(c.status.getResponseDescription()); Serial.println(c.status.code); printParameters(configuration); ResponseStructContainer cMi; cMi = e32ttl100.getModuleInformation(); // It's important get information pointer before all other operation ModuleInformation mi = *(ModuleInformation*)cMi.data; Serial.println(cMi.status.getResponseDescription()); Serial.println(cMi.status.code); printModuleInformation(mi); c.close(); cMi.close(); } void loop() { } void printParameters(struct Configuration configuration) { Serial.println("----------------------------------------"); Serial.print(F("HEAD BIN: ")); Serial.print(configuration.HEAD, BIN);Serial.print(" ");Serial.print(configuration.HEAD, DEC);Serial.print(" ");Serial.println(configuration.HEAD, HEX); Serial.println(F(" ")); Serial.print(F("AddH BIN: ")); Serial.println(configuration.ADDH, BIN); Serial.print(F("AddL BIN: ")); Serial.println(configuration.ADDL, BIN); Serial.print(F("Chan BIN: ")); Serial.print(configuration.CHAN, DEC); Serial.print(" -> "); Serial.println(configuration.getChannelDescription()); Serial.println(F(" ")); Serial.print(F("SpeedParityBit BIN : ")); Serial.print(configuration.SPED.uartParity, BIN);Serial.print(" -> "); Serial.println(configuration.SPED.getUARTParityDescription()); Serial.print(F("SpeedUARTDataRate BIN : ")); Serial.print(configuration.SPED.uartBaudRate, BIN);Serial.print(" -> "); Serial.println(configuration.SPED.getUARTBaudRate()); Serial.print(F("SpeedAirDataRate BIN : ")); Serial.print(configuration.SPED.airDataRate, BIN);Serial.print(" -> "); Serial.println(configuration.SPED.getAirDataRate()); Serial.print(F("OptionTrans BIN : ")); Serial.print(configuration.OPTION.fixedTransmission, BIN);Serial.print(" -> "); Serial.println(configuration.OPTION.getFixedTransmissionDescription()); Serial.print(F("OptionPullup BIN : ")); Serial.print(configuration.OPTION.ioDriveMode, BIN);Serial.print(" -> "); Serial.println(configuration.OPTION.getIODroveModeDescription()); Serial.print(F("OptionWakeup BIN : ")); Serial.print(configuration.OPTION.wirelessWakeupTime, BIN);Serial.print(" -> "); Serial.println(configuration.OPTION.getWirelessWakeUPTimeDescription()); Serial.print(F("OptionFEC BIN : ")); Serial.print(configuration.OPTION.fec, BIN);Serial.print(" -> "); Serial.println(configuration.OPTION.getFECDescription()); Serial.print(F("OptionPower BIN : ")); Serial.print(configuration.OPTION.transmissionPower, BIN);Serial.print(" -> "); Serial.println(configuration.OPTION.getTransmissionPowerDescription()); Serial.println("----------------------------------------"); } void printModuleInformation(struct ModuleInformation moduleInformation) { Serial.println("----------------------------------------"); Serial.print(F("HEAD BIN: ")); Serial.print(moduleInformation.HEAD, BIN);Serial.print(" ");Serial.print(moduleInformation.HEAD, DEC);Serial.print(" ");Serial.println(moduleInformation.HEAD, HEX); Serial.print(F("Freq.: ")); Serial.println(moduleInformation.frequency, HEX); Serial.print(F("Version : ")); Serial.println(moduleInformation.version, HEX); Serial.print(F("Features : ")); Serial.println(moduleInformation.features, HEX); Serial.println("----------------------------------------"); Grazie mille per l'aiuto -
credo che il problema dipenda da questo:
Pin D8 is esp8266 pin 15. This pin is one of the boot configuration pins and for use on a dev board, it must be pulled down at boot. So the NodeMcu has a pull down circuit on this pin and internal pullup is weaker then this external pulldown.Ho provato anche con una SoftwareSerial su D0,D1 (rx,tx)
#include <SoftwareSerial.h> SoftwareSerial mySerial(D0, D1); // RX, TX arduino //HardwareSerial Serial2(2); LoRa_E32 e32ttl100(&mySerial);ma restituisce questo error:

Ciao Taribo,
mi dovresti dare anche il modello esatto del modulo LoRa, e prova a rimuovere le resistenze.Prova a seguire il cablaggio del WeMos D1 mini che c’è sull’articolo (i pin sono gli stessi):
Ed oltre all’RX e TX collega anche l’AUX.Ebyte LoRa E32 per Arduino, esp32 o esp8266: configurazione – Parte 3
Comunque così a prima vista mi pare che hai messo M0 e M1 ad 3v invece che a GND.
Ciao Renzo

ho provato sia con un E32-900T30D che un E32-900T20D (testati con arduino funzionano).
Effettivamente M0 e M1 erano sul 3v3 ora li ho messi su GND, ho provato con e senza resistenze.
adesso ho messo L’E32-900T30D levato le resistenze e:
se cablo D7 e D8 non si carica lo skatch mentre con la SoftwareSerial su D0,D1 mi da:

You must uncomment the LoRa_E32_DEBUG define.
But connect the AUX pin also, or better do a complete connection, so we trust about the HIGH and LOW of M0 and M1.
