Hardware for KNX-RF about knx HOT 3 CLOSED

Just a small info:
I have bought a LaunchPadXL CC1310 and two CC1310 modules and already created PlatformIO support for the CC1310: https://github.com/nanosonde/platform-ticc13x0
This uses the "Energia" (a.k.a Arduino) CC1310 core from TI.
You can use VS Code with PlatformIO and the TI XDS110 debugger with included openocd to upload and debug the code.

I have already created some example which can receive KNX-RF frames. :-)

Small remark:
It would have been better to use the CC13x2 variant as it offers much more RAM.
Support for WMBUS (and therefore KNX-RF [WMBUS S-Mode]) is supposed to be added in Q4/2020.
(see https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz/f/156/p/943948/3487873#3487873)

CC1312:

• 352KB of in-system Programmable Flash
• 80KB of ultra-low leakage SRAM. The SRAM is protected by parity to ensure high reliability of operation.
• 8KB of Cache SRAM (Alternatively available as general-purpose RAM)
• 256KB of ROM for protocols and library functions

CC1310:

• 128KB of In-System Programmable Flash
• 20KB of Ultra-Low-Leakage SRAM
• 8KB of SRAM for Cache (or as General-Purpose RAM)
• ??? KB of ROM for protocols and library functions

According to the FAQ here there is no increase of current in standby-mode for SRAM retention, although there is 4x more SRAM:

Do the CC13x2 and CC26x2 devices consume more power as compared to CC13x0/CC26x0?
Our measurements show that total power consumption for typical BLE use cases remains on par with or slightly improved over first generation CC13xx/CC26xx wireless MCUs. One notable improvement is the total standby current consumption remains at around 1uA with the full 80kB of SRAM and CPU registers retained. The CC13x2 and CC26x2 have standby current consumption equivalent to CC26x0 devices despite the 4x increase in SRAM. For low duty cycle applications powered from coin cell batteries, this can, for example, make the difference of several years of additional battery life.

Closing this for now. If somebody wants to add a new HW idea, please re-open as deemed required.
