Hi, I'm plugging an ESP32 into an evaluation kit.

[env:nodemcu-32s] platform = espressif32 board = nodemcu-32s framework = arduino lib_deps = sparkfun/SparkFun Swarm Satellite Arduino Library@^1.1.10 monitor_speed = 115200

I have connected to the JTAG headers Captura de pantalla de 2023-02-20 00-28-40

1-I have downloaded the swarm library for arduino. But I can't connect to the hardwareSerial or SoftwareSerial. I have tried in various ways to make it work without success.

2- When executing a simple HardwareSerial code defining the baud and the pins (RX, TX). I can connect to the modem without problems and read the information returned by the eval kit. But even so, I do not receive a response from the commands sent by the serial2 port, since if I send a $FV*10 I do not get the expected response. I only see a $RT RSSI=XXX message every 5 seconds in the serial2.read()

This example shows how to:
Set the rate for the $GN geospatial information message
Set up a callback for the $GN message
Print the unsolicited geospatial information messages from the callback

Simple serial hardware code

`#include

define RXD2 16

define TXD2 17

void setup() {

Serial.begin(115200);

Serial2.begin(115200, SERIAL_8N1, RXD2, TXD2);

}

void loop() { while (Serial2.available()) { Serial.print(char(Serial2.read())); } }`

Response $RT RSSI=-110*1d $RT RSSI=-110*1d $RT RSSI=-110*1d $RT RSSI=-110*1d $RT RSSI=-110*1d $RT RSSI=-110*1d $RT RSSI=-110*1d $RT RSSI=-110*1d

I send a $RT ?19 by Serial2.Println to stop the command from being sent by the modem. But the modem still sends me the response of $RT 513 (do you understand me??)

I followed the example of DHT20 sensor. But it didn't work for me.
