Thanks for your feedback, I’m happy that you have resolved your issue, in the next time I publish my shield, but I already worked on Arduino Mega one and surely I need to test It. If you like I need help on my site too.
Keep in touch RenzoI check with my Arduino Mega, and my error is that I don’t use a correct RX pin as Arduino guide describe.
https://www.arduino.cc/en/Reference/softwareSerial
Not all pins on the Mega and Mega 2560 support change interrupts, so only the following can be used for RX: 10, 11, 12, 13, 14, 15, 50, 51, 52, 53, A8 (62), A9 (63), A10 (64), A11 (65), A12 (66), A13 (67), A14 (68), A15 (69).
Now I can send without problem and receive without problem on my Mega without any freeze.
I use this configuration
SoftwareSerial mySerial(11, 5); LoRa_E32 e32ttl100(&mySerial, 3, 7, 6);Now work correctly.
Please update the libray, uncomment
#define LoRa_E32_DEBUG
And send me your log, I try to understand.
If you want to use HardwareSerial you must do like so
LoRa_E32 e32ttl100(&Serial2, 3, 7, 6);Bye Renzo
I’m doing some test with mega and there is a problem, I’m going to discover in the next week.
Bye RenzoI tested the example with a1 case but work for me and my Arduino UNO, I’m going to try with Mega.
Thanks for your patience RenzoHi fransolomon,
I tested your sketch with 2 Arduino UNO, and It’s work correctly, I only add the correct configuration, please try It.#include "Arduino.h" #include "LoRa_E32.h" // SoftwareSerial mySerial(11, 10); // LoRa_E32 e32ttl100(&mySerial,5, 7, 6); SoftwareSerial mySerial(4, 5); LoRa_E32 e32ttl100(&mySerial, 3, 7, 6); //LoRa_E32 e32ttl100(4, 5, 3, 7, 6); void printParameters(struct Configuration configuration) ; void setup() { Serial.begin(9600); delay(500); // Startup all pins and UART e32ttl100.begin(); ResponseStructContainer c; c = e32ttl100.getConfiguration(); Configuration configuration = *(Configuration*) c.data; configuration.ADDL = 3; configuration.ADDH = 0; configuration.CHAN = 0x04; configuration.OPTION.fixedTransmission = FT_TRANSPARENT_TRANSMISSION; configuration.OPTION.wirelessWakeupTime = WAKE_UP_250; configuration.OPTION.fec = FEC_1_ON; configuration.OPTION.ioDriveMode = IO_D_MODE_PUSH_PULLS_PULL_UPS; configuration.OPTION.transmissionPower = POWER_20; configuration.SPED.airDataRate = AIR_DATA_RATE_010_24; configuration.SPED.uartBaudRate = UART_BPS_9600; configuration.SPED.uartParity = MODE_00_8N1; e32ttl100.setConfiguration(configuration, WRITE_CFG_PWR_DWN_SAVE); printParameters(configuration); Serial.println("Hi, I'm going to send message!"); // Send message ResponseStatus rs = e32ttl100.sendMessage("Hello, world?"); // OK The message is received on the other device // Check If there is some problem of succesfully send Serial.println(rs.getResponseDescription()); } void loop() { // If something available // Serial.println("continuity test point"); //This instruction is not executed unless you comment on the previous line "Serial.println(rs.getResponseDescription());" if (e32ttl100.available() > 1) { ResponseContainer rc = e32ttl100.receiveMessage(); Serial.println(rc.data); // Is something goes wrong print error if (rc.status.code != 1) { rc.status.getResponseDescription(); } else { // Print the data received Serial.println(rc.data); } } if (Serial.available()) { String input = Serial.readString(); e32ttl100.sendMessage(input); } } void printParameters(struct Configuration configuration) { Serial.println("----------------------------------------"); Serial.print(F("HEAD : ")); 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 : ")); Serial.println(configuration.ADDH, DEC); Serial.print(F("AddL : ")); Serial.println(configuration.ADDL, DEC); Serial.print(F("Chan : ")); Serial.print(configuration.CHAN, DEC); Serial.print(" -> "); Serial.println(configuration.getChannelDescription()); Serial.println(F(" ")); Serial.print(F("SpeedParityBit : ")); Serial.print(configuration.SPED.uartParity, BIN);Serial.print(" -> "); Serial.println(configuration.SPED.getUARTParityDescription()); Serial.print(F("SpeedUARTDatte : ")); Serial.print(configuration.SPED.uartBaudRate, BIN);Serial.print(" -> "); Serial.println(configuration.SPED.getUARTBaudRate()); Serial.print(F("SpeedAirDataRate : ")); Serial.print(configuration.SPED.airDataRate, BIN);Serial.print(" -> "); Serial.println(configuration.SPED.getAirDataRate()); Serial.print(F("OptionTrans : ")); Serial.print(configuration.OPTION.fixedTransmission, BIN);Serial.print(" -> "); Serial.println(configuration.OPTION.getFixedTransmissionDescription()); Serial.print(F("OptionPullup : ")); Serial.print(configuration.OPTION.ioDriveMode, BIN);Serial.print(" -> "); Serial.println(configuration.OPTION.getIODroveModeDescription()); Serial.print(F("OptionWakeup : ")); Serial.print(configuration.OPTION.wirelessWakeupTime, BIN);Serial.print(" -> "); Serial.println(configuration.OPTION.getWirelessWakeUPTimeDescription()); Serial.print(F("OptionFEC : ")); Serial.print(configuration.OPTION.fec, BIN);Serial.print(" -> "); Serial.println(configuration.OPTION.getFECDescription()); Serial.print(F("OptionPower : ")); Serial.print(configuration.OPTION.transmissionPower, BIN);Serial.print(" -> "); Serial.println(configuration.OPTION.getTransmissionPowerDescription()); Serial.println("----------------------------------------"); }And please recheck your connection schema with the schema on the article not on Github library, and check that you have the last version of the library, I fix sometings 2 days ago.
Bye Renzo
Hi, I can’t check the sketch now, but please refer to my site, i update all the schema.
In the next few days I check all with my Arduino mega.
Thanks to write, and please wait.
Bye RenzoHi I check your sketch and seems quite ok.
But I think you must add AUX pin or put a pull up resistor on It, with no AUX not work for me, but with aux I have a correct send.

you can use ArduinoJSON library, (I’m going to publish a post on how to use It).You can
DynamicJsonDocument doc(512); // Set the values in the document doc["energyLifetime"] = 21698620; doc["energyYearly"] = 1363005; String buf; serializeJson(doc, buf); ResponseStatus rs = e32ttl.sendMessage(buf);Remember you have a size limit on message size of the lora E32.
The code is untested, but I think It can be usefully to understand.
Tell me if It’s ok.
Bye Renzo
Hi Michiel
now It’s possible to check the status with
if (pcf8574.begin()){ Serial.println("pcf8574 started!"); }else{ Serial.println("pcf8574 not started!"); }or
if (pcf8574.digitalWrite(P7, startVal)){ Serial.println("Write ok"); }else{ Serial.println("Write not ok"); }It’s also possible to get last writeStatus with
uint8_t getTransmissionStatusCode() const { return transmissionStatus; }bool isLastTransmissionSuccess(){ return transmissionStatus==0; }Bye Renzo
