- it was too expensive compared to other BLE and WiFi capable SoCs or combinations of chips.
- x86 compatibility doesn't matter.
- power draw (~1W) is too high for the places where one would want to use this SoC.
- the Yocto -based SDK was a mess. Every feature had a caveat and it was a pain to build.
- there was never a clear commitment from Intel that they would make these in bulk for manufacturing.
The new hotness are the Espressif (ESP32) and MediaTek (mt7697) SoCs.
- low power draw (~300mW), even lower at sleep (50mA - nA depending on what kind of sleep),
- SDK is FreeRTOS based,
- the "MCU features" like GPIO, PWM, etc, actually work all the time.
