https://devzone.nordicsemi.com/f/nordic-q-a/38980/stm32f-nrf24l01-tx-problemHi. I&#39;ve been trying to send a payload with STM32F but I can not. I&#39;ve used both STM32F103 and STM32F3 to send a payload but neither of them worked. However, when I use an Arduino Uno as a transmitter and STM32F as a receiver everything works perfectlyen-USTelligent Community 13Wed, 03 Oct 2018 19:35:39 GMThttps://devzone.nordicsemi.com/thread/151550?ContentTypeID=1Wed, 03 Oct 2018 19:35:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:971a5871-de67-4b7b-957d-a2e7bcaa3580Kenneth<p>I suggest to enable the features for test.</p> <p>Kenneth</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/151546?ContentTypeID=1Wed, 03 Oct 2018 19:05:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:41341922-fe56-4887-a042-9cb4f131ebe7PIC16F84A<p>Hi.<br />Yes, I have set the power up bit and added a delay. (2ms)<br />Dynamic payload and auto-ack features are de-activated on both sides.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/151160?ContentTypeID=1Tue, 02 Oct 2018 08:02:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:304cb790-a700-41c2-8877-5a60f4806fadKenneth<p>Have you also set the pwr up bit and waited &gt;1.5ms before calling TX_mode? Is the receiver setup with dynamic payload length or fixed payload size?</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>
