Can be 433mhz rf- module to replace change 868mhz module (RFM69 PI), and if you can then do I need to make a module software changes?
The software changes are easy, just set
frequency = 868 in emonhub.conf. This can be done via the Emoncms ‘config’ module in local Emoncms
A 433Mhz module can be ‘forced’ in software to run at 868mhz, this will result in reduced performance (range).
Changing the 433Mhz hardware module for an 868mhz module will involve de-soldering which is tricky to do (but not impossible) without damaging the unit.
In the next production run of RFM69Pi (due in 1-2 months), we will look at getting a few RFM69Pi modules from the factory with no RF module, therefore any frequency module can be fitted.
As well as a new antenna cut to operate at 433 MHz. (165 mm)
The existing antenna can be replaced, or wire can be added to bring it to the correct length.
Thank’s Glyn, very nise , I hope that I removed the module intact.!
Thanks. I have modules which get the right length measured.
