I have a BLE feed from Arduino - but can not access the data from processing sketch on macbook pro, neither of two bluetooth devices seems to have any accessable data - “/dev/cu.Bluetooth-Incoming-Port” nor “/dev/tty.Bluetooth-Incoming-Port”.

Same need. I heard about BLE 4.0 library… but I cant be able to find it.

Haven’t used bluetooth direct from PC for a while, on Windows-XP it was never very good. Go around the problem: Buy [usb-ttl converter](https://kunkune.co.uk/shop/accessories/usb-to-ttl-ft232rl-ftdi-serial-adapter-converter-module/?gclid=Cj0KCQjw4omaBhDqARIsADXULuUnYRtzg3Pyhd-g65rtJ8aEuNjHALYf_m_8ttE3obm5HpH-xBEefEUaAmpXEALw_wcB) (that’s just the first one I found, not recommending that shop or price). Connect that with 3 wires to HC05. You’re probably familiar with HC05 and other BT adaptors. Now on your PC/Mac you have the BT data on a normal (virtual) serial port. Correction, 4 wires, VCC, 0V, TX, RX.

@RichardDL Have you used this with BluetoothLE?

@svan, Thank you. Regret had not realised that there is Bluetooth and Bluetooth LE. I have several HC05 and they are not all the same. Also some similar, possibly JDY-10. Quick search on Ebay shows this [HC05](https://www.ebay.co.uk/itm/385134585448?hash=item59abcf6668:g:EJUAAOSwn9djJjff&amdata=enc%3AAQAHAAAA4KHVa2zoj25hfVLZMINNCTs68c%2F2EUAzWyQC8oqqAmSqrBYmoajEbnkH1BP2u%2FMKCqGYlhP5KHmHH1z96MYwCUcDx4KsRqaMwW5DcwqNBwBQXw7Z9LLHUliE3mC3NqriYw9hai3TCpWLeSmuvAVjVJRulFBs0jZjfoUorp%2FOeUD5LH%2F4bpoKE5ZF4XSxObQ9zdbGT7XNbjyIwmZdJfZ3yWf67jdmCcdf3QpbHbO%2Bopc2EpLTxSCHecnzofooFGtMD%2BtpoDMxeGrvhZ9PZv%2BfvAvzEg2CmcGLTa5fEEJ6RBLw%7Ctkp%3ABFBMhIiW4Pdg) and this [JDY-10](https://www.ebay.co.uk/itm/114327632702?hash=item1a9e753b3e:g:yNYAAOSwQeJfIPVP&amdata=enc%3AAQAHAAAA4KuXOpUsY7yR%2FvKo83%2FhY40QE9NpVAyu%2FDvPgGu98N7CK1wZiOurzB3xT43a5o0LiM9dPaGxRtOU1XiNV7rm1GgD2URD4CdesJrizWY%2ByOsWQqkwa%2FREN1pgyVwTowsvp%2F9NlAPI%2F%2FxfkYuVKDWv7lt99HfBNtPQEqNKYSbsqfD56o8%2B1yZCcAPq2d2EA7aZ49Ru%2BJOw4Yoz%2FpDBl3ZlOqOzUZ71eyhBDdMN0odagKm%2F0hZI9gxULu6Z3OsMJeIUX1BOJe%2FjWHDYYCPE%2F%2BW6%2F9%2F6Ltq3XS9pImfFglYXax8O%7Ctkp%3ABFBMwpz64Pdg&autorefresh=true) claim BLE. (Ebay descriptions are not always totally accurate.) If you can buy a serial-to-BLE module then you can use the usb-to-serial adaptor to talk to it.
