Tasmota Serial Bridge SerialSend not working

Config:
GPIO1 - SerBr Tx
GPOI3 - SerBr Rx
Ardiuno nano Rx, Tx

When Iam using Serial Bridge Hassio-ESP- Arduino the SerialSend is not gouing trough.
Boud rate is 115200

  1. Receiveing data from Arduino Nano is ok (SSerialReceived):
    {“topic”:“tele/s_9/RESULT”,“payload”:"{“SSerialReceived”:"{I:13.44,P:3092.28}"}",“qos”:0,“retain”:false,"_msgid":“1169269.36d65d9”}
  2. Sending MQTT msg is not gouing thru to the arduino nano. When I send the message from the Hassio the message can be seen on the ESP log, but not received on the arduino. This log is from ESP console.

19:55:59 MQT: stat/s_9/RESULT = {“SerialSend”:“Done”}
19:55:59 MQT: stat/s_9/RESULT = {“SerialSend”:“Done”}
19:56:00 MQT: stat/s_9/RESULT = {“SerialSend”:“Done”}

  1. If I sending messge with the IDE console to the Ardunio, that massage is sending back to the ESP and MQTT.

19:54:23 MQT: tele/s_9/RESULT = {“SSerialReceived”:“I received: 49I received: 10”}
19:54:27 MQT: tele/s_9/RESULT = {“SSerialReceived”:“I received: 49I received: 10”}
19:54:29 MQT: tele/s_9/RESULT = {“SSerialReceived”:“I received: 49I received: 10”}
19:54:32 MQT: tele/s_9/RESULT = {“SSerialReceived”:“I received: 50I received: 10”}
19:54:34 MQT: tele/s_9/RESULT = {“SSerialReceived”:“I received: 49I received: 10”}
