Hello all,
I've bought two si4438 modules (44381C mounted on a XL4463SMT PCB).
I've downloaded WDS to make a radio_config file (well, I've tried several files actually).
And so far, I couldn't get any good results.
Before you ask, yes, I did the logic level conversion between 5v and 3.3v, and my test were done while plugged to my computer through USB, so I doubt it's a power issue.
No luck at all with Radio Head library (init failed).
Poor results with Zak Kemble's Si446x library (his ping server/client got me a very high rate of timeout/invalid and the packages who got through had very low dBm).
So, here's the big questions :
- Has anyone here been experimenting with this chip ?
- Has anyone here been successful with this chip ?
- How to make si4438 work with Arduino UNO?
(If you are going to complain about it, please make it a constructive feedback, or find somewhere else to vent)
