I’m sure that in your test you are getting 0% error rate but in my case I wonder why I have not this result.
If my afsk programmation paramters were wrong I would not be able to receive any packet and if my code were wrong It would be not working either in gmsk.
So I wonder where that could be coming from and it is critical for our application. Would you suggest me to reconsider the ax5043 programmation parameters ?
How are you assessing the packet loss, with what tool and over how long ?
what is the RSSI level on this testbed ?
what freq is being used?
Have you tried to replicate using the AX Radio Config Utility default settings ?
If yes, can you please provide a tar ball of the project directory for us to run a diff and validate ?
If you can choose GFSK or AFSK, then choose GFSK.
AFSK used in old legacy application, it has disadvantage over noise environment.
When the number of adjacent stations with strong signals, you risk “losing” the tuning.
Hello Martin
I would also like to do some tests with AFSK.
I have the testboard DVK-2c and the software AX-RadioLAB v2.11a but i can’t select AFSK in the selection menu. Do I need another AX-RadioLAB version?
best regards

This is available by entering “1962” into the TX periodic field in the main window and click enter.
At that point, AFSK shaped modulation (and others) are available from the PHY window of RadioLab.
Hello Martin
I have now made various tests. The 1200 Bps with Mark/Space 1200/2200 Hz work very well. Also 600 Bps with Mark/Space 600/1200Hz work very well. However, I would now have an application working with 2400Bps with Mark/Space 1200/2400 Hz and that works very poorly. Only every 4 or 5 data transfers work. I still tried 4800 Bps with Mark/Space 2400/4800Hz. This works as bad as the 2400 Bps.
Do data rates greater than 1200 Bps not go with the AFSK modulation in principle, because this was not developed for it or do I do something wrong?

Good day.
I have now made a few more experiments with different Mark and Space frequencies. 2400 Bps on air work with different frequencies. Mark=2400 Hz and Space=4800 Hz works. Mark=600 Hz and Space=2400 Hz also works.
But Mark=1200 Hz and Space=2400 Hz does not work.
But if I change the mark frequency to 1000 Hz or the space frequency to 2800 Hz it works again.
There is a bug in there somewhere.
best regards
