Error message "Could not initialize BlueNRG Mesh library!", error code = 2 when using pre-built bin file for NUCLEO-L476RG with X-NUCLEO-IDB05A1

I also built firmware from provided sources and libraries using WorkBench but the problem persisted. One thing was different, bin file was less than half the size of the pre-built one. I added some code to display returned error code (2) and also dis...

ST7580 transmitter/receiver circuit question

In the ST7580 application note (AN4068) the transmitter and receiver paths are connected through a DC blocking capacitor after the output of the power amplifier. Therefore when no transmission is occurring the output of the PA should be similar to a ...
