No access to STS1TX following power-up

Now and again, following power-up, we find the STS1TX in our product in a state where we cannot interface with it. The SPI and GPIO lines are outputting ~2V levels, so no commands can be sent.Typically, cycling power may allow the chip to initialise ...

Resolved! High current draw on BlueNRG-LP STEVAL-IDB011V1

Hello,I'm doing some development work with an STEVAL-IDB011V1 dev board. I'm targeting very low power and so I would like to verify the numbers listed in the datasheet.In DEEPSTOP mode at room temperature, I am expecting something around1 μA of suppl...

BLE Mesh without storing network data to NVM

I am trying to acheive a BLE Mesh system where no network data will be stored to NVM, i.e. system will need to reconfigure on every reset.The network consist of one PRV and a handfull of LPNs, the LPNs will be mobile and will therefore enter and leav...

Resolved! Port X-CUBE-BLE2 code to BLUENRG2-M2SA

Hi, We are developing a project with BLE connectivity, and we are leaning on using BLUENRG-M2SA as a network coprocessor, with a STM32L476 MCU as the host processor. We have been experimenting with X-NUCLEO-BNRG2A1 ( that has BLUENRG-M2SP on it ), an...
