Hey, guys!
I'm looking for Bluetooth shield with MFI support for iOS ( as cheap as possible ). Does anyone know any?
I've found Adafruit nRF8001 shield and it supports SPP ( unexpectedly because BLE does not support SPP ) but it's custom service written in BLE firmware and only SPI is available. In brief, it's like UART but not UART (no Rx/Tx pins on bluetooth shield to wire to Arduino Rx/Tx pins directly) so it would not work for sketch uploading most likely.
I would buy Bluetooth 2.1 arduino shield with MFi support to be discoverable from iOS devices (with SPP support).
