Hello,
I just got Seeduino v4.2 that has a Grove connector on TX, RX pins and Grove BLE v1.0. I managed to interface between the Seeduino and iOS device using ArduinoBlue library. However, ArduinoBlue makes use of SoftwareSerial library, so the TX, RX pins of BLE dongle are connected to pins 7, 8 (or can be some other) on Arduino. It is of course tempting to plug the Grove connector directly into the Grove TX,RX port on the Seeduino.
However, at least the way I tried it, the communication is rather noisy.
This is my first experience with BLE. Can one connect BLE dongle’s TX, RX directly to TX, RX of Arduino?
Thank you.
