I will try with 0001 , but when , after change jumper in configuration mode ?

Question, on ardunio i must write hex or Binary from your firmewer.
Were im wrong.

catalinosonesti
It is exactly the same program in different file format.
If it sends data to terminal You have programed Arduino correctly.

I see 2 other issues here:
1. Arduino doesn't receive any data from radio. You have to check connection between arduino and pin 2 of connector at back of the radio.

Arduino program waiting for data from radio, that's why it is hanging. When it would receive any data it should display something (if it is wrong data, it should display error).

2. It seems there is a bad connection between arduino and radio board. Check conncetion between arduino pins A2, A3, A5 and radio (purple, light green, light blue in my manual).

I will try with 0001 , but when , after change jumper in configuration mode ?

Always read instructions on the terminal and change jumper when it tells you to change.

I give start from 0003 but terminal start with 43 still runing but the last 2 digits not find.
I know is not ok code tu start wih 43xx for rns 315 ,
I write again ardunio with Avrudeess program but no work .
I put Foto.

As I said in my last post I suspect a connection problem. Check conncetion between arduino pins A2, A3, A5 and radio (purple, light green, light blue in my manual).

In my video (23th second: https://youtu.be/iBxp6z6CybY?t=23) you can see I'm turning central knob and current state changing HIGH -> LOW -> HIGH. It should be the same in your case. If not you have connections problem most likely.

And one more thing, it should be obvious, but did you connect radio GND to Arduino GND?

[catalinosonesti]

No ,NO ,no ....
I see on your pictures pinout black , for gnd but i not put in aplication .
I will try , but now i go in Germany and next week i try with GND from radio to put on arduino gnd .
thank you again .

Hi
Now i put GND on ardunio , start Terminal , start navi and stop to 0000......
Not mesage on terminal just stop to find 0001... , i mean no jump to other step to give me mesage ,, code no korect,,

You still have a problem that Arduino doesn't receive any data from radio.
When jumper is in normal mode it should be resistance about 1k between connector at back of the radio and pin 30 (RXD) of atmega328.


The Second problem is connection between arduino pin A4 and radio (check BC337 transistor connection). This is responsible for entering code (button OK on display).

Hi , again ,
Today i check conector on back and i have 2,98 around 3k , and i mesure the rezistor and i see in your manual is 0.59k my mistake i put 59k , this valuve 0.59k is not so usualy value.
I ask you PCO rezistor , what and were is conect?
I think there is problem .
I think i will do this navi .
thank you for all your suport

this valuve 0.59k is not so usualy value.

You don't have to use exactly the same value. Every resistor around 500 Ohm should be OK.

I ask you PCO rezistor , what and were is conect?

If I understand your question correctly:
This resistor is needed only when you use function for eeprom protecting or eeprom reading function. This is decribed as optional connection on my manual.

[catalinosonesti]

Now i see , they send me BC547 not BC 337 , shure is not the same .
I order today the corect Transistor.

[catalinosonesti]

Hi
How know the value from this resistance 120 ?
k i think

[mbi]

Hi
How know the value from this resistance 120 ?
k i think

It is 120 Ohm (120 Ω).

[catalinosonesti]

OK
Big tks .
I try today with bc337 and jump to step 1 put it 0000 tell me code nich korect apear safe 2 but no future .STOP safe 2 .

[catalinosonesti]

For MBI what can be the problem .
i post video .https://imgur.com/a/WvAnA86 ,as you can see i have TX all the time 0 .
