#Transmit power software

Since that is logarithmic from the distance you will notice that small increase of the distance between receiver and transmitter causes a much bigger change on RSSI. For example noise, dust, and generally environmental conditions will affect the RSSI. It is the logarithmic value depended on the distance also and the medium between transmitter and receiver. Regarding the RSSI, you will not have same accuracy in every distance and always you will have fluctuations. Follow the link below to find datasheet, documentation and HW collaterals for the module: Since you are using a module on your design, we also have a DA14531 module, namely DA14531 SmartBond TINY™ Module! It has very small dimensions and is very low power. Programmable transmit output power from -19.5 dBm to +2.5 dBm.TX: 3.5 mA, RX: 2.2 mA (system currents with DC-DC, VBAT_HIGH =3 V and 0 dBm).Fully integrated 2.4 GHz CMOS Transceiver.The DA14531 has configurable Tx power as well.

There is no software roadmap support for DA14580 product family and SDK5. We have a lot of code examples and improved documentation, and there is also software roadmap support. If you are starting a new design, we would strongly recommend to start with DA14531 or DA14585/586 products and our latest SDK6.0.14, as it is much more improved. -20 dBm output power in “Near Field Mode”.

TX: 3.4 mA, RX: 3.7 mA (with ideal DC-DC).

The DA14580 does have configurable Tx power. Can I ask if there any specific reason why you are using DA14580 module in your design?
