  The young stellar object [BHB2007]-1 has been extensively studied in the past
at radio, millimeter, and infrared wavelengths. It shows a gap in the disk and
previous observations claimed the possible emission from a forming sub-stellar
object, in correspondence to the disk gap. Here, we analyze a set of 8 Karl
Jansky Very Large Array (VLA) observations at 15 GHz and spread over a month.
We infer a slowly variable emission from the star, with a $\sim 15 \text{-}
20\%$ circular polarization detected in two of the eight observations. The
latter can be related to the magnetic fields in the system, while the
unpolarized and moderately varying component can be indicative of free-free
emission associated with jet induced shocks or interaction of the stellar wind
with dense surrounding material. We discard any relevant short flaring
activities when sampling the radio light curves down to 10 seconds and find no
clear evidence of emission from the sub-stellar object inferred from past
observations, although deeper observations could shed further light on this.
