Hi Renzo,
I just replaced the E32 modem with the new E220 ones but I’m getting some problems, in serial I see this:

Hi Fabio,
as you can see at these linesAvailable buffer: 0 structure size: 11 ---------------------------------------- HEAD : C0 0 8It seems that sometimes the device does not give a response, try to add more amperage to the device.

It’s the same circuit I used for the E32, I just replaced the modem.
I tried putting the voltmeter tips on M0 to test MODE_3_SLEEP but I noticed it never goes to zero.In addition, I noticed that the RX and TX pins are considered -1 !!
I’ve done other tests.
I have added two lines in your function in the library:LoRa_E220::LoRa_E220(SoftwareSerial *serial, byte auxPin, byte m0Pin, byte m1Pin, UART_BPS_RATE bpsRate) { DEBUG_PRINT("TX pin from call: "); DEBUG_PRINTLN(txE220pin); this->txE220pin = txE220pin; this->rxE220pin = rxE220pin; this->auxPin = auxPin; this->m0Pin = m0Pin; this->m1Pin = m1Pin; this->ss = serial; this->hs = NULL; this->bpsRate = bpsRate; }And I get:
���Avvio ModemTX TX pin from call: -1 RX MIC ---> -1 TX MIC ---> -1 AUX ---> 5 M0 ---> 16 M1 ---> 15 Init AUX pin! Init M0 pin! Init M1 pin! Begin ex Begin Software Serial Begin MODE NORMAL! AUX HIGH! Complete! Init TX OK Setto in SLEEP il modem: MODE SLEEP CONFIG! AUX HIGH! Complete!

Hi Fabio,
you must try to do a simple circuit on a breadboard and check your devices.
But If I remember you were forced to make a particular circuit due to resistance problems on your devices.Try a simple check and give feedback.

At the end on the gateway (two modems one for TX and one for RX) I use SoftwareSerial for Transmitter modem and HardwareSerial on Receiver so I can use the Buffer.
But I have a strange problem, sometimes it happens that I no longer receive messages.
I have to put the E220 modem on a TTL / USB converter and with the eByte program do a “Reset” by clicking on the “Param Reset” button then put it back on the PCB and it works ….Do you know why? Is there some sort of reset in your library? Because when it happens it’s boring, I have to unsolder the modem, reset it and then resolder it.
But if this happens in production, I would have to go to the field and it’s really hard to do the work on site.-

Oh ok.
Yes I have created two function:void CommunicationAbiot::setReceivingMode() { ResponseStructContainer c = e220ttl->getConfiguration(); Configuration configuration = *(Configuration *)c.data; configuration.ADDL = ID_NODE; configuration.ADDH = 0x0; // MAX 0xFF=255 configuration.CHAN = CHANNEL; configuration.SPED.uartBaudRate = UART_BPS_9600; configuration.SPED.airDataRate = TX_TO_NODE_AIR_DATA_RATE; configuration.SPED.uartBaudRate = UART_BPS_9600; configuration.SPED.uartParity = MODE_00_8N1; configuration.OPTION.subPacketSetting = SPS_200_00; configuration.OPTION.RSSIAmbientNoise = RSSI_AMBIENT_NOISE_DISABLED; configuration.OPTION.transmissionPower = POWER_22; configuration.TRANSMISSION_MODE.enableRSSI = RSSI_ENABLED; configuration.TRANSMISSION_MODE.fixedTransmission = FT_FIXED_TRANSMISSION; configuration.TRANSMISSION_MODE.enableLBT = LBT_DISABLED; configuration.TRANSMISSION_MODE.WORPeriod = WOR_2000_011; // configuration.CRYPT.CRYPT_H = CRYPH_TX_TO_NODE; // configuration.CRYPT.CRYPT_L = CRYPL_TX_TO_NODE; ResponseStatus rs = e220ttl->setConfiguration(configuration, WRITE_CFG_PWR_DWN_SAVE); c.close(); e220ttl->setMode(MODE_2_WOR_RECEIVER); delay(1000); } void CommunicationAbiot::setSendingMode() { e220ttl->setMode(MODE_0_NORMAL); delay(100); ResponseStructContainer c = e220ttl->getConfiguration(); Configuration configuration = *(Configuration *)c.data; configuration.ADDL = ID_NODE; configuration.ADDH = 0x0; // MAX 0xFF=255 configuration.CHAN = CHANNEL; // 0x19; configuration.SPED.uartBaudRate = UART_BPS_9600; configuration.SPED.airDataRate = NODE_TO_RX_AIR_DATA_RATE; configuration.SPED.uartBaudRate = UART_BPS_9600; configuration.SPED.uartParity = MODE_00_8N1; configuration.OPTION.subPacketSetting = SPS_200_00; configuration.OPTION.RSSIAmbientNoise = RSSI_AMBIENT_NOISE_DISABLED; configuration.OPTION.transmissionPower = POWER_22; configuration.TRANSMISSION_MODE.enableRSSI = RSSI_ENABLED; configuration.TRANSMISSION_MODE.fixedTransmission = FT_FIXED_TRANSMISSION; configuration.TRANSMISSION_MODE.enableLBT = LBT_DISABLED; configuration.TRANSMISSION_MODE.WORPeriod = WOR_2000_011; // configuration.CRYPT.CRYPT_H = CRYPH_NODE_TO_RX; // configuration.CRYPT.CRYPT_L = CRYPL_NODE_TO_RX; ResponseStatus rs = e220ttl->setConfiguration(configuration, WRITE_CFG_PWR_DWN_SAVE); c.close(); e220ttl->setMode(MODE_0_TRANSMISSION); delay(100); }

It seems all correct, did you try to change the device?
I get that behavior with a broken device.The next test is to put a new device and not save the configuration, It remains active since you reboot or change It again.

Maybe I found: I have atmega2560 normally in sleep and when I receive a message the modem wakes me up the MCU.
I raise the message and go back to sleep for 10 seconds, then wake up and transmit.
During the 10 second sleep I do not send the modem to sleep and perhaps this is the problem, because during these 10 seconds there are other communications in the air and I see that the aux pin goes low so it receives them.
If, on the other hand, I put the modem to sleep then it no longer blocks.
I believe that if the modem sends a message to the MCU but the MCU is not responding the modem could hang.
Now I have done some short tests, I will do longer and more thorough tests.In your opinion, can this really be?
P.S.: I use SoftwareSerial not HardwareSerial -

OK it’s good.
Before I call you I do some more tests so I have more documentation.
One question though: why is the resetModule () function half commented in the library? -
