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Started today with my STEVAL-STWINKT1B, with default firmware and an outdated version of ST BLE Sensor app.I was happy, the app connected and I was able to do a first trial, gather some data and export the data as csv by email.After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...
