RE: ESB and nrf_esb_read_rx_payload() is returning a positive rssi value

Thank you. Just reread my post and the correction to the code should be

m_rx_fifo.p_payload[m_rx_fifo.entry_point]->rssi = - NRF_RADIO->RSSISAMPLE;

Apologies

Hi Mahendra,

Thanks for the heads up. It’s correct that the value from NRF_RADIO->RSSISAMPLE is read as a positive value while the actual received signal strength is a negative value. It would therefore make sense that the ESB code converts the value from positive to negative, or document it clearly that the actual RSSI is negative. I will report this to the developers.
