trying to send and receive the data through can bus moduler using with nrf9160 and esp32 controller (using SPI)

Question

Hi,

can anyone help me with this situations that i'm facing from a 1 month so i'm connecting esp32 controller to seengreat RS485 Dual CAN Bus moduler and the other hand i'm connecting nrf9160 to seengreat RS485 Dual CAN Bus moduler but i can't send or receive any messages through this and i attach the both screenshot from nrf serial terminal and from esp32 controller terminal and also i attach my overlay code and my both project files. i tried with 125,250,500 KBPS bus speed but i didn't make it and this can bus moduler have 16MHZ and it has 120 ohm resister attached with the moduler and i tried spi-max-frequency = <125000>,<250000>, <500000>, <1000000>.WACS (2).zip WACS_esp32 (2).zip

here is my overlay file code

// can mcp2515 drivers overlay

&pinctrl {

spi3_default: spi3_default {

group1 {

psels = <NRF_PSEL(SPIM_SCK, 0, 13)>,

<NRF_PSEL(SPIM_MOSI, 0, 11)>,

<NRF_PSEL(SPIM_MISO, 0, 12)>;

};

spi3_sleep: spi3_sleep {

group1 {

psels = <NRF_PSEL(SPIM_SCK, 0, 13)>,

<NRF_PSEL(SPIM_MOSI, 0, 11)>,

<NRF_PSEL(SPIM_MISO, 0, 12)>;

low-power-enable;

};

/ {

chosen {

zephyr,canbus = &mcp2515;

};

&spi3 {

compatible = "nordic,nrf-spim";

status = "okay";

pinctrl-0 = <&spi3_default>;

pinctrl-1 = <&spi3_sleep>;

pinctrl-names = "default", "sleep";

cs-gpios = <&gpio0 25 GPIO_ACTIVE_LOW>;

mcp2515: can@0 {

compatible = "microchip,mcp2515";

reg = <0>;

spi-max-frequency = <250000>;

int-gpios = <&gpio0 17 GPIO_ACTIVE_LOW>;

osc-freq = <16000000>;

bus-speed = <250000>;

status = "okay";

};

// UART overlay

&uart2 {

status = "okay";

current-speed = <115200>;

};

i spend too much time on this and still didn't get anything from this so please help me to get through with this and what else i can do for debugging cuz i change the wires many times and now i order new can bus moduler to get confirmation about that is the moduler don't have the problem or what, i don't know

thanks
vivek
