How to test integrity of RMII link between STM32F417's Mac and an external Phy?
I have a product in which a STM32F417 (BGA) micro is attached to a LAN8720A (QFN) Phy using the RMII interface. It uses an external 50MHz oscillator going to the Phy and STM32.For testing newly assembled PCBs in mass production, is there a way to tes...
SensorTile BLE GATT Characteristic Editing
Hi,When editing the GATT characteristic in the provided software for the SensorTile, I cannot increase the size of the payload being transmitted. Even after altering the charValueLen variable, this doesn't appear to affect the length of the packet be...
Should Pin 21 of BLUENRG-M2SA be grounded?
Hello,I am using the BLUENRG-M2SA in my design. In the BLUENRG-M2 datasheet at https://www.st.com/resource/en/datasheet/bluenrg-m2.pdf, it is stated that all GND pins must be grounded. However, in the BLE module integration design guidelines (DT0142)...
[NUCLEO-WL55JC] FSK Modulation - WakeUp from Sleep mode
Hello,I really like the NUCLEO-WL55JC platform as it provides many features for FSK which I am using, but when I checked the UM, I didn't find a way to wake Up the MCU by receiving a Frame. From my experience, there should be a mode different than RX...
Readout Protection
Hello,is it possible to enable/disable the "readout protection via SWD/JTAG mode for BlueNRG devices? Is it possible with openocd?BR Sebastian
STEVAL-IDB008V1M ADC Input 1 & 2 connections
Hello, I've been using the STEVAL-IDB008V1M to help develop an BLUENRG-M2 product for an company. I've noticed in the schematic there are 3pF capacitors connected to the ADC Input 1 and Input 2Does anyone know why this is done?For the time being I ha...

Change TX data length with BlueNRG M2 in network co processor mode
I am using BlueNRG M2 in a network co-processor mode and want to send 10 packets per second, each of 100 bytes. I have generated code through STM32CubeMX and changed the ATT_MTU value from 23 to 247 in the bluenrg1_gatt_server.h file, which was gener...
BlueNRG-M2 Host-less mode
Dear all, I'm just getting started using a BlueNRG-M2 module and a host STM32.Browsing through the documentation I've seen that chapter 3.2 of bluenrg-m2 datasheet mentions "Host-less mode (application processor): customer application runs on the Blu...
