Hello, I am a beginner in node red and would like to save the data from the dht22 sensor in mysql and display via chart. I have already tried a lot but unfortunately without success.
Hi,
Got it working!
It was a strange mix of RFM69/RFM69HW devices (all soldered into the nrf2rfm69 board - so couldn't tell which type it was) and also a faulty RFM69. Also, it seems the signing consumes much processing power (and memory) to the little at328 chips. A sketch with more than 65% memory usage may fail some signatures, so not recommended to put many functionalities in the same node, specially when running my_debug.
Simple sketches just with a sht21 sensor are working fine with signing and RFM69 encryption.
Copying the correct HMAC, soft-serial and AES to the mysensors.conf file and with RPI reboots after each config/make/makeinstall cycle solved the problem.
Thanks,
Joaoabs

Maybe MySensors isn't yet ready for 64bit
It won’t be until someone wants it badly enough, and has the time and skills to do whatever is needed.
You seem to have made some progress. Hopefully you or someone else can figure out how to proceed.
@ncollins said in High power consumption NRF52832 & SI7021:
NRF_TWI0->ENABLE = 0;
NRF_TWI1->ENABLE = 0;
thanks, added those lines after reading and an appropriate .begin prior and it compiled and sent and works so far.
Won't know about consumption for a while - it doesn't act up while I'm watching it... it seems to get stuck at some point (1 week? 2 weeks? 10 days?) and then dies. And yes, it is set to reboot every 24 hours
So it's something else you or I have not pinpointed yet.
I admit I'm not a programmer neither a computing expert.
But this article here says that "Generally speaking, 32-bit programs can run on a 64-bit system, but 64-bit programs will not run on a 32-bit system."
My understanding is that if I compile MySensors GW in a 32bit RasPI OS and copy & run it on RasPI 64bit OS it will likely work (I'm guessing I'll also have to copy some libraries, so not so simple as copying the binary).
This can be the option for those who want to use MySensors in 64bit RPIs like myself. I'll be using IoTStack on a RPI4 4GB 64bit with zigbee2MQTT and honestly wasn't happy with the idea of having a second RPI just for MySensors GW.
I'll try it during the weekend and share results here.
