One of Fourteen Data... Datas? One of fourteen is wrong

PlatformIO IDE
1

This is ESP Now. The problem must be in the receiver, because the sender is printing the correct number to Serial.
It’s readingId: readingId = readingId + 1;

The receiver was printing a huge number. I fiddled a bit, and it went to zero. But dig this:
ID value: 1.74
readingID: 0
Is the response to:

  Serial.printf("ID value: %4.2f \n", myData.readingId);  
  Serial.printf("readingID:   ");
  Serial.print(myData.readingId);

Now it’s consistently 1.74 AND 0.

?
Any idea what goes on here?

One of the pods was read correctly. I forget which one. Pod 1 and Pod 3 are out of commission. But two of the pods’ “reading ID” was consistently wrong.

This is the receiver code. It’s been here before.
I can’t see any place where “readingId” could be modified.

So if readingId is an unsigned int, why print it as a double with no data conversion? Passing an integer to the %f double/float format specifier (source) is undefined in behavior in C/C++. You should consistently use %u to print it for unsigned (int).

1 Like
3

That % stuff was just added, to match format with the rest of the serial print stuff.

That % stuff gives me 1.74.

The straight stuff gives me 0.

That straight stuff gave me something like 1743202187355 before my last fiddle.

The actual number being sent is an actual number that goes up by 1.

The ESP32 is pulling a number out of its nose.

That’s the only data type mixing, right?

Should it be

"(“ID value: %u \n”, myData.readingId);

?

4

Yes.

Your stack is trashed after %f tries to pull a 64-bit value off the stack but you only gave it 32-bit (your unsigned int). The print output after that makes no sense.

5

Okay. But I added that stuff. I already had the zero from the regular stuff.
Why zero instead of the reading number?
How can I get it to report the readingId again?

It used to work.

6

But, is it a value different from zero?

Can you provide a hexdump of the received packet (pointer incomingData, length len) using Arduino_HexDump/HexDump.h at master · Yveaux/Arduino_HexDump · GitHub?

Along with what it prints from your code (after correcting the %f)?

7

Haha- can I what?
I’ll look at it.

8

No, I can’t make any sense out of that, can’t understand how I would put that in my code.
Just insert those functions somewhere??

9

Yes, prefarably at the top, then call the function HexDump like the function signature intends.
