Hi all, I am wondering if you can help with a very newbie question.
I have bought a develop board with Q24PL001 modem. I want to have a test to see if it is fine. The modem is soldered to the board according to the guide. The jumpers are kept unchanged in the original positions. The dev board is connected to the PC via the provided serial cable.
Open Microsoft HyperTerminal, choose COM1 or COM3, set bit rate 115200, then I type AT in the window, unfortunately, I can’t see any response from the modem.
What could be wrong in my test?
Thanks for your information in advance.
