setConfiguration and "check wiring" #2

Closed ChadMatsalla closed 2 years ago

ChadMatsalla commented 2 years ago

I'm using a E220-900T22D. Version: E220-900T22D-V1.X

I'm using an esp32.

I'm trying to use your example SetConfiguration program.

If the program looks like this:

#include "Arduino.h"
#include "LoRa_E220.h"

HardwareSerial serial2(1);
LoRa_E220 e220ttl(32, 33, &serial2, 35, 26, 25, UART_BPS_RATE_9600, SERIAL_8N1);

void printParameters(struct Configuration configuration);
void printModuleInformation(struct ModuleInformation moduleInformation);

void setup() {
    Serial.begin(115200);
    e220ttl.begin();
}
void loop() {
}

I see:

RX MIC ---> 32
TX MIC ---> 33
AUX ---> 35
M0 ---> 26
M1 ---> 25
Init AUX pin!
Init M0 pin!
Init M1 pin!
Begin ex
Begin Hardware Serial
PIN SELECTED!!
Begin 
MODE NORMAL!
AUX HIGH!
Complete!

This seems good. But If I run the entire program using the constructor above and using this as loop():

void setup() {
    Serial.begin(115200);
    e220ttl.begin();
    ResponseStructContainer c;
    c = e220ttl.getConfiguration();
    Configuration configuration = *(Configuration*) c.data;
    Serial.println(c.status.getResponseDescription());
    Serial.println(c.status.code);

    printParameters(configuration);

    ResponseStatus rs = e220ttl.setConfiguration(configuration, WRITE_CFG_PWR_DWN_SAVE);
    Serial.println(rs.getResponseDescription());
    Serial.println(rs.code);

    c = e220ttl.getConfiguration();
    configuration = *(Configuration*) c.data;
    Serial.println(c.status.getResponseDescription());
    Serial.println(c.status.code);

    printParameters(configuration);
    c.close();
  */
}

I see a ton of things as follows:

I've checked the wiring and used two different E220s and two different esp32s.

Can you please help me understand what I'm doing wrong?

Thanks,

Hi Chad, probably It's a power supply problem, try to add 5v and good amperage to the device and give me feedback. Bye Renzo

ChadMatsalla commented 2 years ago

Hi Renzo,

I'm writing this here for future visitors.

When I wrote the above I was using 3.3 out of the ESP32. After I read your response I switched to the 5v output out of the ESP32 and saw the same. I switched to an external 5v power supply and I saw, amoungst many other things:

This was the description of the attempt to set the configuration (Success)

So for future readers, the E220-900T22D is rather particular about it's power supply.

Thanks Renzo!

This is unrelated, but I can't get the two systems to communicate. They have the same configurations: Client:

AddH : 0
AddL : 0

Chan : 23 -> 433MHz

SpeedParityBit     : 0 -> 8N1 (Default)
SpeedUARTDatte     : 11 -> 9600bps (default)
SpeedAirDataRate   : 10 -> 2.4kbps (default)

OptionSubPacketSett: 0 -> 200bytes (default)
OptionTranPower    : 0 -> 22dBm (Default)
OptionRSSIAmbientNo: 0 -> Disabled (default)

TransModeWORPeriod : 11 -> 2000ms (default)
TransModeEnableLBT : 0 -> Disabled (default)
TransModeEnableRSSI: 0 -> Disabled (default)
TransModeFixedTrans: 0 -> Transparent transmission (default)

Gateway:

TransModeFixedTrans: 0 -> Transparent transmission (default)

I don't have actual antennae - I inserted a 3.25" piece of wire into the SMC connector. They are sitting ajdacent to each other in a breadboard.

I found no information in whether you can use these without an antenna.

Do you have any suggestions?

Thank you!

Hi Chad, with transparent transmission, they should work. I don't know why the communication doesn't work. Bye Renzo
