According to the Concept2 Bluetooth Smart documentation at http://www.concept2.com/files/pdf/us/mo ... nition.pdf (page 14), the Sample Rate characteristic (i.e., 0x0034) is supposed to be read/write, but it appears to be read/notify only.
* When I interrogate the PM5 using the LightBlue iOS app, the 0x0034 characteristic is identified as read/notify only.
* When I attempt to write to the 0x0034 characteristic in a custom iOS app, I get an error.
* I can read the 0x0034 characteristic -- it is always 0x01, which corresponds to a 500ms sample rate
Has anyone successfully written to PM5's BTLE Sample Rate characteristic (0x0034)?
I'd like to have updates more frequently than every 500ms.
Thanks!
