We're just completing a design based on the ST BlueTooth Low Energy module SPBTLE-RF.
However, we are finding it very difficult to find any stock (in the UK at least)
SPBTLE-RF is marked as not recommended for new designs
SPBTLE-RFTR looks ok and appears to be just a different format (Tape & Reel)
But delivery times are anything from 5 weeks to a year !
Nucleo development boards for BLE are still featuring this module so I presume it isn't going to be superseded anytime soon ?
Thanks for any info anyone may have..
