aci_gatt_update_char_value returns 0x20 which is not defined
A call to the GATT Update function aci_gatt_update_char_value gives me the return value 0x20 which is not defined in bluenrg_def.h - so what does it mean? The update fails.
STM32WB5MM Footprint
I'm looking to port a prototype from an STM32WB55 Nucleo board/custom daughter board combo to a single custom board using an STM32WB5MM module. I've done some digging but can't find a recommended footprint for this module. Does anybody know if one ...
BLUENRG stuck when writing BLUE_CTRL registers
I'm working on a custom board with a BLUENRG-2. I'm able to flash and erase with the UART and the SWD pins, but none of the programs work. When I debug it step by step, I find out that all programs hang on this line, when it writes on the BLUE_CTRL r...
What is the difference between memory types connected over FSMC or FMC ?
Hello everyone,I'm using stm32f407 that provide FSMC to be able to interface with synchronous and asynchronous memories and I want to extend the memory so, What is the difference between memory types •NOR Flash/PSRAM/SRAM , the NAND Flash/PC Card an...
Issue in STM32F746 - KSZ8863 interface
I'm trying to use a KSZ8863 Ethernet PHY with the STM32F746G. We have used the RMII interface to connect with KSZ8863 and running at 50MHz frequency .RMII pins are connected to KSZ8863 based on MAC mode interface.To test the KSZ8863 ,We have used stm...
Ble Receiving Junk data
hi all i am using blenrg2 m2sp chip as network mode. its operating as peripheral device and communicating with host controller through UART with 115200 baud rate .I received BLE read characteristic request , i did not response till 1 second ...
S2-LPTX module different supply levels for analog/SMPS and digital
Hi!I am designing my own sigfox board using S2LPTX module, some sensors and a ST microcontroller. Microcontroller and sensors are working on 1.8 V supply. I know that S2LPTX module can work with VBAT = 1.8 V, but in section 3.2 it mentions VBAT shoul...
Hello, I have problem with connection between JLINK and custom board with BLUENRG_LP chip.
I have BLUENRG-LP chip on my custom board and I'd like to flash beacon example inside. The example is one from BlueNRG-LP-DK-1.0.0 named BLE_Beacon.As the debugger I try to use JLINK (tried CMSIS-DAP configuration as well) but I'm not successful.This...
