Hi. If somebody can help me. I am trying to connect 2 ESP32s with 2 TJA1050 transceivers. One is sender and the other one is receiver. Using the sample sketches. Default pins. Connected to 5V and using logic shifter. One logic shifter connected from one ESP32 and shifting for both ESP32s. From osciloscope the voltages are on TX - 3.52V and 3.56V ESP32 side and the TJA1050 5.23V and 5.31V. RX voltages 3.11V and 2.86V ESP32 side 5.25V and 5.0 V TJA1050. CAN H - 2.52V - 4.05V, CAN L - 1.09V - 2.62V. Tried before without shifter. Saw some videos on youtube where it was working withou logic level shifter. But the sender stop sending. When I press reset on receiver then the sender sends one messages and again stops. Receiver newer get the message. Serial baude rate 9600. Arduino IDE 2.3.6
