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...
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 ...
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 ...
Hello,I have a problem with the bluenrg-2. I'm using a STEVAL-IDB008V2.I measured the current while in different sleep state and here are the results :CPU-HALT : 1.6 mAWAKETIMER : 1.9 mANOTIMER : some nA.The problem is that I'm supposed to have some ...
Started today with my STEVAL-STWINKT1B, with default firmware and an outdated version of ST BLE Sensor app.I was happy, the app connected and I was able to do a first trial, gather some data and export the data as csv by email.After that, I did an up...
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...
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...
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 ...
