I read your next blog and think it is swell. Keep up the great work.

Okay, I believe I have solved the puzzle as to why the EnOcean Pi receiver is not picking up the Temp, Magnet Contact Transmitter Module or the Switch Module from the EnOcean Sensor Kit that was sent to me. Looking at the back of the Switch module, it is listed as model PTM210 DB PN: S3001-A210-15 where as the one that works has a model number of PTM 210U PN: S3051-A210-S. Looking up the PTM 210 DB on the EnOcean site, it is listed with a Freq of 868 MHz where as the Receiver module I have is a 902 US version. I would suspect these are incompatible and will not talk to each other. I'll have to contact the good folks involved in the contest to perhaps get the Sensor Kit switched out for a 902 version which should work.

Now that is solved I can proceed with the rest of my project.

Still no success with getting the BLE device to enable, but I did find some more info regarding this. Apparently at kernel 4.4.9 there was a switch from ttyAMA0 to serial1; I'm currently running with 4.4.14-v7+. I've gone through a few iterations of updates and reinstall of packages and reverted the settings back to use the UART for the BLE device but the device still will not enable.

This is what I see from hciuart.service status

pi@raspberrypi:~ $ sudo systemctl -l status hciuart.service

Hi Jon,

i got my EnOceanPi 868 to work, including Wifi and BLE. All is described here: [Pi IoT] Alarm Clock #05: EnOcean Pi and Sensors

Good luck!
