I am having some issues with receiving data using the Nordic UART Service. I can successfully connect with a device via BLE, I can write data to the device using the UART service, because when I send e.g "reboot" the device indeed reboots itself. I also can receive data using the Generic Access service - e.g read out the device name. However, I am unable to read from the UARTs TX Characteristic: 6E400003-B5A3-F393-E0A9-E50E24DCCA9E. I suppose, Im having an issue with enabling notifications on the TX line. To my knowledge, there is no similar function in app inventor to e.g Bleak python function - start_notify(). I have also seen a post in this forum, that stated the notifications are automatically enabled while using RegisterX or ReadX functions of BluetoothLE1 extension.
I am using 20200828 version of the mentioned extension.
Thanks in advance for any suggestions.
