Posted on August 14, 2017 at 10:45I have exactly the same problem as https://community.st.com/0D50X00009XkYUuSAN but with different network processor - BlueNRG.We have two custom boards with BlueNRG: one acting as peripheral and one as central.I hav...
Posted on August 11, 2017 at 00:54On SPWF01SA - I need to post JSON to the Webserver backend and update the JSON file...Any hints on how this can be done? I can read the JSON file ok from my webserver but I am stuck at the part where I have to send ...
Posted on June 04, 2017 at 15:15I have been using PIC32 microcontrollers but am looking at switching to the STMicro line of microcontrollers. One thing that Microchip has that is really nice for industrial products is an external PHY chip with a bui...
Posted on August 08, 2017 at 01:57I am trying to demonstrate an over the air firmware update of an STM32L476 (Nucleo) with a X-NUCLEO-IDB041 BlueNRG board. I see the example for the STM32L1xx, but it is very difficult to port as it uses the old Sta...
Posted on August 07, 2017 at 14:05what should be the voltage level for logic high at 'dir' pin of 54ac164245 bidirectional level translator?
Posted on August 01, 2017 at 11:47Dear community,I read on the SPBT2632C2A page here: http://www.st.com/en/wireless-connectivity/spbt2632c2a.html that this IC is NRND.Is there a standard replacement part that would fit my needs i.e. using the SPP ea...
Posted on July 31, 2017 at 10:31What should be the voltage level for dir pin of 54AC164245 for logic high when it is used as bi-directional level translator.It is not clearly stated in datasheet. Should it be 3.3V or 5V ? Please clarify.
