Posted on March 02, 2018 at 16:34Hi,I changed on my hardware the SPWF01 against a SPWF04 module. I communicate with the module via a STM32. If I use the SPWF04 module, I need a pull down resistor at the SPWF RTS output to get the communication worki...
Posted on April 04, 2018 at 07:02Hi,First of all, sorry for the lengthy message.We are developing a 433 MHz transceiver using SPIRIT1. We were able to run 'SDK_BasicGenreic_A' program provided with the development kit on 'STEVAL-IKR002V3D' daughter-...

Posted on April 03, 2018 at 18:43Hi ST team,Looking over the device datasheet, I had expected to see maximum current consumption at least under TX and RX conditions so I can design power management appropriately. When this information is missing, I...
Posted on March 28, 2018 at 17:00I have been able to use the File Print (AT+S.FSP) in some test situations, but now that I'm using it for real I'm not getting any results.When I was performing my feasibility tests I was printing sections from within...
Posted on March 15, 2018 at 07:44Hello and good day!I'm attempting to use the SPWF01SA module with an STM32F0 microcontroller to post some data onto a remote web server. I have come to understand that the AT+S.HTTPPOST command can only post form da...
Posted on March 29, 2018 at 19:19Hello,I'm trying to figure out whether it is possible or not to upgrade the firmware of a host processor connected to BlueNRG-MS.From this http://www.st.com/en/embedded-software/st-blue-dfu.html it seems possible:'Th...
Posted on March 28, 2018 at 17:09I'm looking at the SPWF04 training course which is very good by the way, but it mentions I should refer to 'SPWF04S Power management Application Notes' for more details on the Low power modes.Been unable to find this...
Posted on March 28, 2018 at 13:58Hi!My SPIRIT1 code is not working properly and I found confusing the description of the INTERRUPT_MASK and INTERRUPT_STATUS registers in the SPIRIT1 datasheet (rev 10, Oct 2016). In the registers description both MAS...
Posted on July 26, 2016 at 19:08I am consistently getting this error (+WIND:5:WiFi Hardware Failure:5) and I don't understand why? It is a pain because the module keeps having to be reset and it is impossible to communicate on a socket since this ke...
