HI, I want execute my automation script parallely in multiple devices. I have launch selenium grid and registered two different nodes in selenium grid server. Both devices has been successfully registered as nodes in server. ![](https://discuss.appium.io/uploads/default/original/2X/6/6863987b46e0d0e91b5b222b1855bdbca8be3070.png) After executing script through TestNG my test script is successfully running in one device but for other device I am getting below error. org.openqa.selenium.SessionNotCreatedException: A new session could not be created. Details: Problem getting session data for driver type AndroidDriver; does it implement ‘get driverData’?

Change Parallel= ‘Test’ to **Methods** in Testng xml Hopefully It will work. ---

yes in device settings “install via USB” option is already enabled. Also when we run the script only in one particular device its running perfectly. @bhaskar @Arvind_Patel @Appium_Master. Will you please help me to achieve parallel execution. ---

Actually @SharmaSumit u are not creating 2 different instances of appium . Please open two instance and give separate host 0.0.0.0 and 127.0.0.1and port name 4734 and 4723 Try these with 2 instances and It will work perfectly ---

Hi Vikram, I am facing few problems in appium for a particular functionality automating with CHAT Feature automation. Actually one test case in need to verify in such a way that, i need to login with one device select the user name and send the SMS to that particular person and then i need to switch to another machine with different port number and login and verify the SMS sent and i need to reply for that. Now the real challenge come into picture, where i need to switch back to previous session or previous port and i need to verify the replied SMS. Do u have any idea on this. i am really struggling with it like Regards, Arun ---

@aruns you need start 2 appium servers and start 2 drivers. One connecting to one device another to other device. No you can chat between. I made such solution for payments when i am sending payment from one user to another and return.
