All things seem to be alright, but it just cannot work.

Thanks for your reply.

Hi C,
sorry if i answer only now, but with C name your post go on SPAM and I lost It.

Your speed air rate was different from sender and receiver. I think you must fix It.

Bye Renzo

[C]

Thanks for your reply.

Sorry, I have fixed the air rate. The version I uploaded was not the latest.

All of the parameters are the same now.

[Renzo Mischianti]

Is everything working now? If you want share your project with us.
Bye Renzo

[C]

not really

All of the messages seem to be fine, but the transmission does not work.
I think the problem here may be caused by the hardware, but the message said, “Success.”

It’s really confusing.

[Renzo Mischianti]

Hi C,
The success alert you that the sender device send the message, but it don’t kbow if a receiver receive it.

Try with trasparent or check M0 M1.

Enable debug and retry.

Hi

I’m having the same problem. I’m using two Arduinos with two 868T20Ds, and using wiring and code from the fixed transmission tutorial. Both sender and receiver have the “Success” message and I have both with the exact same parameters, but the message from the sender is never received.

The only thing I have changed is the #define for my frequency, and everything seems to be alright, but somewhere something doesn’t work

Thanks in advance

[Renzo Mischianti]

Hi jorge,
first try to get config to check if it’s all ok.
If all ok retry in trasparent transmission.
Then set configuration with save.
And now resend the message.
If not work try to change pull_up resistot.
Bye Renzo

[Jorge]

Hi, thanks for your reply

I have uploaded the getConfiguration code and I got the message “No response from device! (Check wiring)”, but I’ve checked the wiring and also changed the pull_up resistor and the message it’s still there.

In my case I doesn’t have a 4.7K resistor so I’m using 2x2K + 2×330 + 4×10 resistors in series instead, but I don’t think there’s the problem; I’ve checked them all and they work fine, and that’s the only change I have made from the wiring in the tutorial

[Renzo Mischianti]

Hi,
try to remove the resistor, some device have some different setting.
If problem continue try to change the e32 and execute the same code per try to reset with the EByte usb board.
Bye Renzo

[Jorge]

I’ve fixed the “No response from the device” problem, although it was unplugging the M0 and M1 pins instead of the resistor.

Now, in getConfiguration I have “Success”, as well as in setConfiguration, where I’ve successfully uploaded and saved the configuration in both sender and receiver, but after all of that, I return to my original problem: Everything have “Success” state, but the message from the sender is never received by the receiver

[Jorge]

It have turned really confusing.

I continued testing and now the configuration in setConfiguration is not saving although it’s set for save it. The getConfiguration now returns success as state, but head is different in configuration and moduleInformation. I have tried it with another pair of modules and got the same results.

I think the problem is somewhere around this methods, but I don’t know where is it or nor what I’m doing wrong.

[Renzo Mischianti]

Hi,
I think the better solution is to reset all device with the original software and adaptor.
Sometime when this device not wor tha software is the solution.
Bye Renzo

[Jorge]

Hi,

How can I reset the modules ? Probably this is the case when the solution is to reset them, but I don’t know how to do it

[Renzo Mischianti]

Hi,
I use this device
https://s.click.aliexpress.com/e/_A4tZaa
with the specified program for e32
