Delay of 30ms while transmitting data using RF24 library : arduino or esp with Nrf21L01 module.https://devzone.nordicsemi.com/f/nordic-q-a/65524/delay-of-30ms-while-transmitting-data-using-rf24-library-arduino-or-esp-with-nrf21l01-moduleHi, I am using NRF24L01 with arduino using RF24 library ( https://github.com/maniacbug/RF24 ). While executing the transmission code i have observed the following line takes about 30 to 30ms time delay to execute. radio.write(&amp;charBuf, sizeof(charBufen-USTelligent Community 13Fri, 04 Sep 2020 06:53:05 GMTRE: Delay of 30ms while transmitting data using RF24 library : arduino or esp with Nrf21L01 module.https://devzone.nordicsemi.com/thread/267954?ContentTypeID=1Fri, 04 Sep 2020 06:53:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2b44223b-af2a-4c4e-9111-e8fb4f604e59ketiljo<p>If the radio is powered off, it will take max 4 ms to start up the crystal oscillator. No reason for it to take 30 ms.&nbsp;</p> <p>For the arduino questions, I&#39;m afraid that you have to ask elsewhere.&nbsp;</p><div style="clear:both;"></div>
