ant max trasmission baud rate

[marikalp]

hi guy . I m triyng to understand if could be possible to send a at least 300 hz input signal beetwen two boards nrf52840 with the trasmission protocol ANT.

I tried to use the example of ant broadcast tx and rx with a pin interrupt on a gpio port that open the channle for trasmission in tx ,whlie the rx is on the other board . i changed the channle period on tx from 8192 to 328 but it fails for at least 30 hz...for the rx i tried to set the channel period to 328 too and also to 00 but there was not a visible improvement in the reception speed.

RX:

TX:

THANKs a lot for your answers!!!

Hi,

The minimum interval is about 5ms. If you need to send data faster than 8bytes every 5ms, then you use burst transfer to send larger chunks of data every interval, then you can achieve much higher throughput.

how have to setup the rx and tx channel period in order to have 5 ms? i tried different combination but no one works good

I would think setting .channel_period = 164 on both TX and RX should do the trick? You may start with .channel_period = 328 (10ms) to test with on both TX and RX.
