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
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()

void setup() {
Serial.begin(115200);

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.
