Sending a string in send() - not doing as I want it to do

[mickecarlsson]

Hi,
I have this function in my sketch:

void CheckRSSI()
{
  char SendingRSSI[10];
  char ReceivingRSSI[10];
  char TxPowerLevel[10];
  char TxPowerPercent[10];
  String sendRSSI;
  itoa(RFM69_getSendingRSSI(), SendingRSSI,10);
  wait(200); 
  itoa(RFM69_getReceivingRSSI(), ReceivingRSSI,10);
  wait(200); 
  itoa(RFM69_getTxPowerLevel(), TxPowerLevel,10);
  wait(200); 
  itoa(RFM69_getTxPowerPercent(), TxPowerPercent,10);
  wait(200); 
  // Now, combine all values and send it in
  // Line should look like "T:-90 R:-81 PL:20 PP:100"
  sendRSSI = "T: ";
  sendRSSI.concat(SendingRSSI);
  sendRSSI.concat(" R:");
  sendRSSI.concat(ReceivingRSSI);
  sendRSSI.concat(" PL:");
  sendRSSI.concat(TxPowerLevel);
  sendRSSI.concat(" PP:");
  sendRSSI.concat(TxPowerPercent);
#ifdef MY_DEBUG
  Serial.print(F("RSSI String: ")); 
  Serial.println(sendRSSI); 
#endif
  send(msgRSSI.set(sendRSSI));
}

The output is:

RSSI String: T: -59 R:-51 PL:-2 PP:0
TSF:MSG:SEND,13-13-0-0,s=1,c=1,t=47,pt=0,l=23,sg=0,ft=0,st=1

Why does send() only send 1 instead of the string?
Using 2.2.0-rc.1

How is msgRSSI created?

[mickecarlsson]

// Debug
#define MY_DEBUG
// Enable and select radio type attached
#define   MY_RADIO_RFM69
#define   MY_IS_RFM69HW
#define   MY_RFM69_NEW_DRIVER
#define   MY_RFM69_FREQUENCY RFM69_868MHZ
// #define   MY_RFM69_ENABLE_ENCRYPTION

#include <MySensors.h>

#define SKETCH_NAME    "Test-text"
#define SKETCH_VERSION "1.0"

#define CHILD_ID_RSSI_INFO  1

// Mysensors settings
MyMessage msgRSSI(CHILD_ID_RSSI_INFO, V_TEXT);

void before()
{
}

void setup()
{
  Serial.begin(115200); // for serial debugging.
  Serial.println(F("Start up sensor."));
}

void presentation()
{
  present(CHILD_ID_RSSI_INFO, S_INFO, "RSSI Info");
}

void loop()
{
#ifdef MY_DEBUG
  Serial.println(F("Starting new measurements"));
#endif
  CheckRSSI();
  // Sleep 
#ifdef MY_DEBUG
  Serial.println(F("Waiting 1 minute"));
#endif
  wait(60000);
}

@mickecarlsson sendSketchInfo is missing. Not sure if that affects anything.

The presentation call is strange. I haven't seen it used with three paramters before.
Edit: seems to be my inexperience, so presentation is probably ok.

@mickecarlsson see if changing

  send(msgRSSI.set(sendRSSI));

to

  send(msgRSSI.set(sendRSSI.c_str()));

helps

THANKS!!
That did it:

RSSI String: T: 127 R:-49 PL:-2 PP:0
TSF:MSG:SEND,13-13-0-0,s=1,c=1,t=47,pt=0,l=23,sg=0,ft=0,st=OK:T: 127 R:-49 PL:-2 PP:0
