Good morning
Communication works from Appinventor to M4 metro card with Bluetooth ble communication. On the other hand, nothing is transmitted from the M4 card to Appinventor
Thank you for your help
Cordially

Re: Bluetooth communication problem from metro M4 airlift to Appinventor
First, make sure that the M4 card is configured to send data over Bluetooth. Check the documentation for your specific M4 card to see if there are any specific configuration steps you need to follow to enable Bluetooth communication.
Next, check the Bluetooth settings on your Appinventor device to ensure that it is properly paired with the M4 card. If the devices are not paired, they will not be able to communicate with each other.
If the devices are paired but still not communicating, check that the data format being sent from the M4 card is compatible with the data format expected by the Appinventor app. If the data format is not compatible, the app may not be able to interpret the data correctly.
It's also possible that there may be an issue with the code you're using to transmit data between the devices. Check that the code is properly configured to send and receive data over Bluetooth BLE, and that there are no syntax errors or other issues that could be causing the problem.
If you're still having trouble after checking these issues, you may need to seek out additional technical support or consult the documentation for your specific M4 card and Appinventor device.
