-> Have you connected an external antenna to this module?
-> Please note that if you are using on board PCB antenna ,you have to populate cap (C14) and Inductor (L1) an mentioned in the datasheet ( http://www.cypress.com/file/318881/download page#13).

s1065003_3384576 May 17, 2018 8:09 AM (in response to GyanC_36)Hello,
I'm using on board PCB antenna, I don't know what you said " populate cap (C14) and Inductor (L1) an mentioned ".
Would you explain what that mean?
Thanks

You have to connect capacitor and Inductor which are named as C14 and L1 in the Module schematic to use the on board PCB antenna. Please refer the Module datasheet http://www.cypress.com/file/318881/download page #13 for schematic. Please go through the table placed near the UFL Connector at page#13 of above mentioned datasheet.

s1065003_3384576 May 17, 2018 10:18 AM (in response to GyanC_36)Hello,
I have another question.
L1 didn't soldering on the board, which means on board PCB antenna didn't connect.
Why the board still can connect to CySmart?
