Posted on February 17, 2015 at 11:24Dear All, We designed a RFID reader using the chip CR95HF. We use quite old SRI4K tags. We used the ST lib (lib_SRIX4k.c from the MMY Application Team) that manages this tag. The hardware design follows the typica...
Posted on January 08, 2015 at 23:25Hi, I have a STEVAL-IDB002V1.Which image file to use to update the BlueNRG stack to 6.4. bluenrg_6_4_Mode_2-16MHz-XO32K. img orbluenrg_6_4_Mode_2-16MHz-XO32K_HCI.imgWhat is the difference between them?Thanks
Posted on January 13, 2015 at 23:07On STEVAL-IDB002V1 daughterboard there are JTAG pins connected to BlueNRG(pins 8-11). Is they have any use for user application? #bluenrg
Posted on January 13, 2015 at 16:29Hi, we are designing a VoIP (SIP/RTP) device with a stm32 microcontroller. It must also have WiFi connectivity, so SPWF01 would be a natural choice. However we've run into limitations of built-in TCP/IP stack wh...
Posted on January 15, 2015 at 03:30Hi all,I have a project in which I have to use MICS band for data telemetry in an implantable device. Can I use the SPIRIT1 for MICS band which centers at 403MHz? (I think the TI CC1101 can be configured to do it, ...
Posted on December 19, 2014 at 21:13From the landing page on the SPIRIT1 Radio, if i want to operate 915/922 MHz Band - what is required to get started? Can I use two of the Dongles evaluation modules - STEVAL0IKRV001V5 (on a computer perhaps with ...
Posted on September 29, 2014 at 11:06Hi, I just installed the STSW-CONNECT009 pack, and upon starting the Spirit1 DK I get an error. The error in the error-log.txt is the following: ''local variable 'key' referenced before assignment''Could anyone h...
Posted on November 21, 2014 at 03:44Hi, I am working with evaluation board (STEVAL-IDW001V1) equipped with the WiFi module (SPWF01SA.11), and having trouble with updating the firmware (FW) to the board. I followed the instructions to have BOOT0 hig...
Posted on December 17, 2014 at 10:35Hi all, I'm using the WiFi module to connect to infra WiFi in socket server mode. The module return (through serial link) that connection to WiFi is OK. But sometimes, in the WiFi router interface (a Freebox), the...
Posted on December 18, 2014 at 10:13We are currently developing a product that uses the SPWF01S module running firmware:140623-cd34ea1-SPWF01S.Our product relies on the firstset.cgi to connect to a network, the situation is as follows: A microcont...
