I am running a copy of the Peripheral_UART application on a nRF52 Dev Board (Segger PCA10040)
The device connects to iOS apps (such as nRF Connect and nRF Toolbox.
I can send text data from the toolbox app to the UART RX port (USB com port) of the device but I see no method for sending text from the device to the iOS app.
With a 3rd part app, ESP32 BLE Terminal, I can also connect and send data from iOS to the device but I cannot send data back from the device using the USB com port terminal program.
I need to be able to send and receive text data between the UART port of the device and the iOS app.
Also, the only properties that I see advertised by the device are :
Notify (6E400003-B5A3-F393-E0A9-E50E24DCCA9E)
and WriteWithoutResponse (6E400002-B5A3-F393-E0A9-E50E24DCCA9E)
Please advise
