Hello, I have a custom board with a STWLC38JRM. Everything was fine and I was able to flash it with STSW-WPSTUDIO v1.8.4 through the dev board STEVAL-WLC38RX and FT_SDA/FT_SCL/VBUS/AGND pins. I try to make some test and I disabled internal overtemper...

Hello,When I try to set advertisement delay more than 10000ms, the function aci_gap_set_advertising_configuration return an error 0x82 (BLE_STATUS_INVALID_PARAMS). According to the function declaration, it must be ok:/* .... * @param Primary_Advertis...

Hello,I have a high power consumption during deepstop. The goal is less than 5µA (announced less than 1 in the datasheet).I removed every other chips on my custom board to found the solution. It's a small board.When I enter in deepstop mode (without ...

Hello,I'm doing a new board bring-up and following the document AN5503 (https://www.st.com/resource/en/application_note/an5503-bringing-up-the-bluenrglp-bluenrglps-devices-stmicroelectronics.pdf)At chapter 4 (HS_Startup_time) I use the example firmwa...

Hello,I have a problem with the ST25DV04KC-IE.In the datasheet the register MB_WDG (000Eh) must have a factory value of 0x03 but my chips have 0x1a. Bits 3-7 are RFU in the datasheet. Do you know why there is a difference?The real problem is that I t...

Hello Sebastien,There is an interpretation error from ST. The Core spec 5.2 says 10485 seconds and not 10 seconds. Regards,Jean

Edit: Response not correctI understand.But is there any way to bypass this limitation ? I want to make a very low power device.The BLE link will not be with a smartphone but another proprietary device. Regards, Jean

Hello, It's working with the first remark, thank you ! I does not know that "normal state" init override "sleep state" init.Regards,Jean

Thank I didn't have this doc. I already implemented everything except LSE driving.during my test, UART and debugger are disconnected.Part of the schematic that I can share: IO init:void BSP_IO_Init(void) { GPIO_InitTypeDef GPIO_InitStructure = {0}...

BlueNRG-LP maximum advertisement delay.

[Resolved] Why BlueNRG-LP deepstop current increases with time ?

Why my HS_STARTUP_TIME is so high?

Change value on MB_WDG disable I2C.
