BTW guys, since I bought the pen and if I get it to work, you might be tempted to buy one too so watch out. There’s multiple versions of the pen and one is for china, mainly if it has 3 buttons its china. For now, and I’m not sure if its correct, the BHR7237GL
model seems to be correct one, contrary to BHR7237CN
which by the CN
sounds lot like china while the other being global. @armorica helped me a lot with the info about pen
