serial terminal issues about cc1101-tool HOT 9 CLOSED

Yes, support for dual CC1101 is in my plans. However this is a big change because it requires to add additional parameter for every command. It is not going to be soon but I am thinking of adding such option

from cc1101-tool.

I am using normal Serial Port commands in ESP32
Serial.print(F("Hello world "));
Assuming you have USB-TTL converter that shoud be hard-wired to one of ESP32 serial ports it should work. However ESP32 has 3 serial ports and these should work only for port that is used for Serial debugging in Arduino IDE (maybe it would be good to launch Serial Port debug there ?)
https://esp32io.com/tutorials/esp32-serial-monitor

I am using the same principles as in this example here :
https://deepbluembedded.com/esp32-hello-world-serial-print-arduino/?utm_content=cmp-true

check if this example works for you.

I am currently waiting for ESP32 board delivery, once I get it I will be able to correct the code.

The question is if you are using speed 115200 baud for communication over USB with ESP32 board

In my code you have

void setup() {
// initialize USB Serial Port CDC
Serial.begin(115200);
Serial.println(F("CC1101 terminal tool connected, use 'help' for list of commands...\n\r"));

[...]

void loop() {
[...]
/* Process incoming commands. */
while (Serial.available()) {

it should work as long as you have properly configured putty

You may want to check this description as well - maybe tou need serial to usb port converter as on these pictures : https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/establish-serial-connection.html

through usb serial i do get the "CC1101 terminal tool connected", but if i do it with a USB-TTL converter i don't get nothing of that, just boot logs and im unable to enter anything

ive used 9600 baud, but i'm currently using 115200 and sticking with that

in the example https://deepbluembedded.com/esp32-hello-world-serial-print-arduino/?utm_content=cmp-true , everything worked and the esp32 was able to receive data over usb

BUT i found out that wasn't the issue

it seems that it's not receiving anything because its hanging in the cc1101initialize function, on ELECHOUSE_cc1101.Init()

i get no logs, nothing, but if i get a multimeter i can see that MISO and MOSI are pulled high, 3.3v and SCK is pulled low, 0v

this might be something wrong with my cc1101, so i will order another one

from cc1101-tool.

okay, i've debugged some things here and there and found out it was an issue with my wiring - putting pin 9 on the esp32c3 makes it go into boot mode, and moving those pins to a different area allowed it to boot successfully

also, you were kind of right with the usb to ttl converter, as of currently i am using a usb to ttl coverter to speak with the esp32 usb-cdc was off, i can communicate via usb

(red bracket are added print statements for debugging)

unfortunately, every time i attempt to transmit tx 010203040506070809aabbccddeeff it stays on Transmitting RF packets.
i think i killed my cc1101 in some other way

This looks like CC1101 is not reporting readiness through GDO0 pin state. It may be either broken or the pin assignment is wrong on this CC1101 board. Other thing is TTL level 3.3V compatibility. If 5V compatible ESP board then you may have this issues

from cc1101-tool.

my pin assignment seems to be fine, and the esp32c3's logic is 3.3v

gdo0 is pulled high 2.9v instead of 3.3v, which doesnt seem like a problem but it might be
ordered another cc1101 anyways

from cc1101-tool.

okay, fortunately my wiring was correct, but my pin assignments in the code were incorrect

THIS is the only correct pinout diagram, which is meant to be used with the xiao esp32c3
pins 21 and etc. are not in the official pinout, which is weird, only D0, D1 which are not supported by the script

after editing it in my code, everything worked perfectly

i also edited the setup() function to include ELECHOUSE_cc1101.getCC1101() and some other debug stuff

void setup() {

  // initialize USB Serial Port CDC
  Serial.begin(115200);
  Serial.println(F("CC1101 terminal tool connected, use 'help' for list of commands...\n\r"));
  Serial.println(F("(C) Adam Loboda 2023\n\r  "));

  Serial.println();  // print CRLF

  Serial.println("cc1101 initializing..\n");

  // initialize CC1101 module with preffered parameters
  cc1101initialize();


  if (ELECHOUSE_cc1101.getCC1101()) {  // Check the CC1101 Spi connection.
    Serial.println("Connection OK");
  } else {
    Serial.println("Connection Error");
  }

  Serial.println("cc1101 initialized\n");

  // setup variables
  bigrecordingbufferpos = 0;
}

thank you for your help, everything works now and i can now open car doors and etc.

Please post a portion of source code with your PIN assignments for this ESP8266 board. It would be very useful for others 👍

from cc1101-tool.

code pinout:

// defining PINs set for ESP32 module
byte sck = 8;
byte miso = 4;
byte mosi = 10;
byte ss = 20;
int gdo0 = 21;
int gdo2 = 7;

MOSI and SCK go to their normal spi positions, except MISO, which goes to pin 4
GDO0 goes to pin 7, and GDO2 goes to pin 21
SS/CSn goes to pin 20

also, if you can, will there be any support for dual cc1101s? ex: one for jamming and one for rx'ing? would be pretty cool, there is some examples out there already with LSatan's library too
