The Stokes phenomenon for the $q$-difference equation satisfied by the   basic hypergeometric series ${}_3\varphi_1(a_1,a_2,a_3;b_1;q,x)$
  We show the connection formula for the basic hypergeometric series ${}_3\varphi_1(a_1,a_2,a_3;b_1;q,x)$ between around the origin and infinity by the using of the $q$-Borel-Laplace transformations. We also show the limit $q\to 1-0$ of the new connection formula.
