Namely 1) The Navcom 400 indicates a working Bluetooth connection to PM250, but unfortunately not my heart rate is displayed. The belt was certainly correct gem. the description applied to the instruction manual.
2) The S3 Mini finds the PM 250 only not, after some research on the Internet, the Smartphone Bluetooth 4.0 seems indeed to support hardware, Android can but obviously deal from version 4.3 with Bluetooth 4.0 - on my S3 Mini is currently running 4.1.2, an update is currently not in sight :(
Unfortunately I have no other devices (iPhone, Bluetooth-enabled fitness equipment etc.) within reach, with whom I could test the function. I am doing myself thus somewhat hard to review the PM250. Normally, I would return the product because it is obviously not suitable for my fitness environment, unfortunately, there is no provision at Amazon Vine. I spend the time being, therefore, Article 3 stars and waiting the next Android update from. Then you should change something, I will revise the review.
Tips I take gladly :)
