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.

Posted on July 31, 2017 at 10:03We are looking for a new wifi module. And was thinking of using the SPWF04SA from ST.But now I can see that ST has chosen another wifi module for their STM32L4 Discovery kit IoT node.Does anyone have an Idea why they ...
Posted on August 03, 2017 at 00:40Are there any open bugs related to ID 2131: Slave abruptly disconnects if any non-empy packet is received after an encryption failure?I'm bonding a device with an iPad using the 'just works' model. After clearing t...
Posted on June 24, 2017 at 00:30Dear Colleagues,I'm developing a real time application which I need around 128 kbps of BLE application throughput.Inside BlueNRG package there is a Throughput demo that shows how to implement a simple throughput test ...
Posted on June 29, 2017 at 00:48Hi, I'm using a BlueNRG-MS attached to an STM32l4 via SPI. I've got the connection working all right. When I try to define a custom service with 6 characteristics, the first 2 work fine, but the rest of the aci_...
Posted on July 28, 2017 at 13:42for example the datasheet offers this command'AT+S.SOCKDW=<sid>,<cid> <len><cr>{data}'this is the format if UART is used, but at no point is explained how I do this with SPI! All thats written is:'To map an AT command...
