Hello,The data sheet for BlueNRG-MS specifies the tx power from -18 dBm to +8 dBm. However, the data sheet from SPBTLE-RF, which embeds the BlueNRG-MS, specifies the maximum tx power as +4 dBm. Where does the 4 dB loss come from? Does this mean, tha...
Posted on April 30, 2018 at 13:23Hi, I am attempting to implement a Bluetooth Mesh Network using a ST32F401RE and the NUCLEO-IDB05A1 Bluetooth header. I am wondering if this is possible? As the only example I could find (http://www.st.com/en/embed...

I am using the board STEVAL-ILL083V1 for controlling street light i.e. on/off/dimming. According to the given package it can be performed for individual board. Now I am thinking of to treat STEVAL-ILL083V1 as a node and want to take several such node...
Is the BT controller of BlueNRG products from Nordic or SiLabs or something else? /* Asking because knowing this can be useful to find more info and drivers for these chips */Thanks,-- pa
Hello, I recently buy a new Nucleo-L4R5ZI-P board and I am trying to use it with the X-NUCLEO-IDB05A1 expansion board to develop a BLE application but it is being really stressful because although I am following the guide "Getting started with the ST...

Hi, I designed a board based on SPBTLE-RF few months ago. It seems that the component has been replaced by the SPBTLE-RFTR recently. https://community.st.com/s/question/0D50X00009XkepJSAR/what-is-the-status-of-the-spbtlerf-ble-module-?t=1536147003953...
Little information regarding PCB placement of module is available on line. Even less is available about functioning in the vicinity of other transmitters at 2.4 GHz. Any help is much appreciated!
