Question Description I am having trouble connecting to my Bluetooth Nokia phone Solution Please ensure that the Nokia phone has at least firmware 5.5 on it. Early versions of the Nokia firmware were only designed to work with Nokia Bluetooth devices and so can cause problems. Also ensure that the latest version of Nokia PC Suite for your phone is in use. To find the firmware version currently installed on your phone, please see the phone's documentation.
Question Description Solution How do I upgrade firmware on my BL-521/730? See the above section on how to upgrade firmware Where are the drivers for my BL521/730/819 & 830? You do not need to install drivers for these devices. All the necessary software is on the hardware itself. Brain Boxes products will run at the maximum Bluetooth data rate of 1 Mbaud.
Question Description Solution If you have a BCSP device and require a H4 card (or vice versa), please contact sales@brainboxes.com as we have H4 versions of all our Bluetooth products (with the exception of BL-521, which is in neither mode) What is the difference between BCSP and H4? H4 is the standard way of transmitting Bluetooth data over a UART as defined in the Bluetooth specifications.
Question Description Specifying distances for Bluetooth devices is not prudent, as distances achieved depend very much on the environment. However, in tests at Brain Boxes labs we have achieved distances of over 200m with line of sight and 30-35m in a typical office environment. This is for data transfer, not voice.
