Sending speed

[oparudi]

Hello guys,

I hooked up two RFM69HW each on a STM32 Blackpill board (one sender one receiver) and installed the RFM69-STM32 (brainelectronics) lib. Sending and receiving is working. The sender does a simple radio.send() without an ACK in a loop but it takes about one second for each transmit. I am using Arduino IDE. How can I speed this up? Thanks!

It seems awfully long for a simple packet that normally is flushed out of registers in mere milliseconds at most.
Since I didn't create that library I don't have immediate insight. But AFAIK you should be able to use my library on STM32. Did you try RFM69 LowPowerLab lib?

Hello Felix, I tried your lib and it

...is much faster. By the way: is there a possibility to define all the necessary pins or do I have to edit the lib?

See the RFM69.h definitions, you can add yours there.
