I bought a esp-01 from [Mod edit: suspect link removed] and was getting the same problem, the code was not burning in the esp01 but then i came to know that I am making a mistake, to burn the code in esp8266 the 0 pin should be grounded.
Hi, Samir!
Interest in low-speed PLS modems there still present?
Maybe my modem is interesting?

Hi Samir,
Which transformer did you use?

That looks really great!
I have big interest in this projekt!
What is the state of the firmware?
How does one setup the adress for each Device?
Even I did this project , using his radio head measter code , and the radio head server example , it was a success , didn't test the range still . The problem I have is the range is so low . In our schematic I used a varessistor just in case if there is a voltage spike .
Hi all
I have also been experimenting with the same chip. I have desinged an arduino micro compatible board with built-in PLC module . See picture.
Howver I am getting mixed results when transmitting with the PLC various control packets using software serial port at at 1200 bbs.
Se below a typical example
PLC Out Packet:B C FE FF FE EF FD 1 65 52 68
PLC In: Packet 1ST ATTEMPTĀ : B F FE FF FE EF FD 11 65 52 68 -> wrong - CRC fails
Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā 2ND ATTEMPTĀ : B C FE FF FE EF FD 31 65 52 68 -> wrong - CRC fails
PLC Out Packet: F 1 65 1 52 EF FF FF FF 1 FE 1 1 AF EEĀ Ā
PLC InĀ Packet: F 1 65 1 52 EF FF FF FF 1 FE 1 1 AF EEĀ -> correct
The last two bytes of the packets are CRC bytes to check correct reception of the packet.
Anyone has anything to suggest ?

Very descriptive and to the point your post!

Mr. watcher , I would like to know what were you range test results , mine were soo poor . I Uploaded the Radio head library and made The same schematic which was made by the person who started this topic on this forum, Any suggestions to increase the Range ?

What do you mean by range in this case? If you mean how far apart they are, I have only tested everything within the same room, connected to different mains outlets.

In my case I tested inside the room , it didn't go that far(only to the nearest socket) , what's the schematic you made (As in something close to the Data sheet which NXP have provided or something else ?) and the code you uploaded (I used the Radio head library what did you use )? I'm planning to do this as my final year project in my university hope you'll be able to help with it .

I used the sample schematic given in the datasheet. Look for the isolated version with a transformer and with increased input sensitivity.
As for the code, I am using a particular code which supports a certain protocol that I am using.
First of all try to get communication established. For example send simple bytes from one serial port to the other and have it displayed on the PC. Once this is done, then you can move to something more complex.
Hi Dear Samir,
First, I like your post; however, I can understand your code(radioheadmasterhumanentry)
I am new in Arduino and I want to start Tda5051. Could you help me to send a master and slave sample code with Library?
i only want to have one led and one switch in master and slave board.
Looking forward to hearing from you soon with best regards

Are you have this circuit schematic please
