@selbig Wow thanks for sharing that. I’ve been thinking about BT for some time… and hadn’t seen how far it has come. There is also Blue Tooth Commander App for Android – so good for all types.
I’m just wondering how you are powering it.?
On powering, I’m really looking that it needs to be able to use low power, and then turn on when the CellPhone with BT is nearby and notify the Maylfy. Low Power is a relative term to how much power is available.
Possibly DSD TECH HM-19 CC2640R2F has possibly more support for low power… and as BT 5.0 says could have 4times range. Haven’t looked through it yet.
The Digi Xbee LTE CAT-M1 also incorporates BTLE.
Some other resources I found
