Posted on July 25, 2016 at 07:57Hi,I want to interface X-Nucleo-IDB04A1 (BlueNRG) with STM32F217 (using STM3221G Eval board). I have used the SensorDemo in X-cube-ble1 (for X-Nucleo-IDB04A1 and Nucleo-L053R8 ) and I have re-adpated the files to be c...
Posted on July 15, 2016 at 15:09HelloI use a BlueNRG with a STM32F302x8. To test the SPI I use the AN4494 and it works fine. After a BlueNRG reset I read a Blue_Initialized_Event (04 FF 03 01 00 01) by using an interrupt on SPI_IRQ and the function ...
Posted on July 21, 2016 at 13:33Hello, I managed to setup a full mutual auth TLS system with SPWF01Sx and Nginx server. I have reliability problems to open the socket. Sometimes, the socket opens without problem, sometimes opening fails and I get th...
Posted on July 05, 2016 at 11:06Hi,I can't receive the UDP packets sent from SockTest (SERVER) to the Wi Fi module (CLIENT).I connect the Wi Fi module via TeraTerm, configure it and then sent an ''AT+S.SOCKON=192.168.32.255,4999,u,ind'' to prepare t...
Posted on July 20, 2016 at 21:24Hello, I am running Windows 10 and I am trying to figure out how to test the one-way authentication in the application note AN4683. I have apache and openssl downloaded but I need help creating the certificate/key and...
Posted on July 20, 2016 at 18:16HelloI need help pleaseI use a SPBT2632C2A Bluetooth module with an arduino nano. I use both for sending sensor data to an application on an android tablet.All work well but I can not find how to set a FIXED PIN code ...
Posted on July 17, 2016 at 12:35Hello, Doing the Example 1 of the AN4683 (TLS Example 1, mutual auth), all commands work without problem (keys and certificate generation), same for imports in Wifi module (send back ''OK'') But the last command : AT+...
Posted on July 19, 2016 at 19:45When monitoring the SPI bus on the IDB002V1, I notice that polling stops for 3 to 6 mS every time a Command Complete Event is received. This slows down how fast we can send commands to the BlueNRG. Is there any way ...
Posted on July 13, 2016 at 14:56Is it possible to perform a HTTP DELETE or HTTP PUT through the AT commands (without opening socket etc.). Is it possible using the custom request command AT+S.HTTPREQ? I have found no example of how to use AT+S.HTT...
Posted on July 14, 2016 at 20:18While I await some expert help on the question about a packet sniffer for the STack protocol, can anyone describe what is the ACK in the STack protocol? What does it look like (i.e. does it have a preamble and/or sync...
