Unexpected error from BlueNRG-MS when calling aci_gap_init()
Hello,I am porting the BlueNRG-MS to use a non ST based MCU and believe I have most of the porting issues resolved but am receiving a surprising error code when running the BLE_Beacon sample.I am using the BLE_Beacon sample as stock as possible. Thi...
Can the BlueNRG-2 chip be programmed through SWD?
I have the STEVAL-IDB008V2 board, and it programs decently through the ST-Link V2. However, I am facing troubles with programming the BlueNRG-2 chip through SWD of another Disco board. Can anyone please tell me whether the BlueNRG-2 can be programmed...
How to design the SMPSFILT associated with the SMPS built into the BlueNRG-2 module?
Hello there!I am struggling to find any significant information about the SMPS built into the BlueNRG-2. It would be really great if some more details are made available regarding the internal hardware and the external auxiliaries and supporting circ...

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 ...
Why discovery end event is missing from BlueNRG-2?
Hi,I use my device for continuous scanning. The scanning is started by calling:aci_gap_start_general_discovery_proc( 2000 /*LE_Scan_Interval = 1.25 s */, 1800 /*LE_Scan_Window = 1.125 s */, 0x00 /*=use public dev ad...
S2-LP transceiver
I want to develop 6LOWPAN over S2-LPThis mesh network have other devices that support 6LOWPAN, different to ST microelectronic manufacturer. Could I tune S2-LP in frequency, band, modulation, etc in order to can speak/listen with other devices?Best r...
