Problem wih the SWD frequency speed in order to flash a BlueNRJ-232 chip.

Hello all,I am using in my project a BlueNRG-232 chip in order to have a bluetooth function. I would like to speed UP the flash frequency of my BlueNRG chip. Currently I am limited to 50kHz and it is impossible to go up. I am using a st link programm...

STEVAL-IDB005V1 and STEVAL-IDB006V1 problems

I have an STEVAL-IDB005V1 that will not enumerate as a serial port on either Windows 7 or Windows 10 so I can't use the GUI to update the Bluetooth stack. Any help would be appreciated.I also have an STEVAL-IDB006V1 that does enumerate but does not ...

BlueNRG-LP can't run to main function.See the picture,Every time it runs to here(PUSH instruction),the mcu get into stuck,i dont know why.Please help,the problem bothers me a long long time.

There are any way to establish comunication between STMF746 and the PC using the LwIP + RTOS to send and reciving data independently (without handsakeing question/anser)?

I am using the LwIP + RTOS to establish communication between STMF746 and the PC. I was able to send from STM to PC, or from the PC to STM, but I only could be able to do one thing. There are any way to program the STM to be working by 2 thread: one ...

Best approach to send large chunks of bytes using BlueNRG-2 on STEVAL-STWINKT1

Hello all!I have a STEVAL-STWINKT1 board and I have created my custom services and characteristics to be able to send to a Raspberry Pi an uint8_t array of 240 bytes.From the RPi side, I am using bluepy to connect to my board and receive the notifica...

Problems with TX using S2-LP - without HAL libraries

Hi there,I'm running into some weird problems while trying to use the S2-LP transceiver. It seems as though the transceiver is only sending one byte each time it enters TX mode.I am writing a program for a heavily storage-constrained project and as s...

Why does BlueNRG-1 wake up once 10 seconds?

I used BlueNRG-1 to make 1 minutes wake-up timer. But it seems wake up once 10 seconds. It causes current consumption more about 1.5uA. How to solve it? Detail information is at attach file. My code snipped is as follows. #define SCAN_RESPONSE_TIMER ...

BlueNRG-M2 idle power consumption too high

I am building a non-connectable beacon using a BlueNRG-M2SP board, and an STM32L412 MCU as a host, and the power consumption of the M2SP board between advertisment phases is around 24 uA, which is over 10 times higher than what the datasheet says (2....
