Introducing MySensors on nRF24LE1
-
Quick question on the topic of using the nRF24LE1 as a platform.
Can the AES accelerator be used in order to sign messages?Thanks.
-
No, AES is used for encryption. The HMAC/SHA256 signing format MySensors use, has no benefit of AES.

@Anticimex : Thanks for the quick response. I have got my terms mixed there, thanks for clarifying.

@Diogo-Salazar You are welcome :)

First impression of MySensors running on nRF24LE1. Reporting temperature / humidity from DHT22, VCC voltage and millis() timer.
This SoC has many interesting features (SPI, 2-Wire, Serial, GPIO, ADC, RNG, AES accelerator, etc. ) and sub uA sleeping modes - without the need to solder a RF module. However, flash size limited to 16kB - still more than enough for many (peripheral) sensors... :)
Readings in MYSController:
Compiling with SDCC and nRF24LE1 SDK.

@tekka Hi! I'm trying to assemble this setup :-)
Could you provide the wiring diagram (humidity sensor and NRF).
Do you have an updated code?@ykhokhlov would like to get it going as well, have a requirement for a tiny form factor, have had one of these in the drawer forever.

@chickey @ykhokhlov This was a POC I did a few years ago and never updated the code nor did I do further development on the library due to limited interest. There are way better alternatives available nowadays, i.e. nrf51/nrf52.
-
@tekka Thanks for the answer and suggestion. Did you develop a POC of a MySensors node for the nrf51/nrf52?
@ykhokhlov There are a ton of not just POCs but also fully functioning mysensors nrf51/nrf52 nodes on openhardware.io Just click and have a look for yourself.
