I have some questions. I try to integrate a Grove BLE v1 device from Seeed. I see two options:
- using the standard Grove cable
- attach the cables direct to the board.
First option. The SoftwareSerial library is not working for my Sodaq Sara R410 board. Port A6/A7 cannot be used....any suggestians or do I need to rewrite the library?
Second option. First question, do I need to connect the Tx with Rx or Tx with Tx??? Second queston, after succesfull soldering, using the standard passthroug script which uses standard D0/D1 ports can be used to run AT commands?
Or...if both options are not working, does anybody have good suggestions?
