Does anyone have advice on how to go about finding (if it exists) a closed form for
$$\sum_{n=0}^{\infty}\frac{J_n(n)}{n!}$$
Where $J_n$ represents the Bessel function of the first kind; numerically it appears to converge to $\approx 1.68226...$
I tried playing around with the recurrence relations for the Bessel functions in an attempt to find an exponential generating function for $J_n(n)$, but this lead to nonsensical results. Any other ideas?
