Posted on June 28, 2016 at 10:00Hello, again. In SPIRIT1 datasheet, in section of synthesizer band, especially for divider value, there are four values, i.e. divide-by-6, by-12, by-16 and by-32. But in File SPIRIT1-Library, which is part of SPIRIT1-...
Posted on June 27, 2016 at 10:52Hi All,I am new in BlueNrg but not in developing C and I want to work withNUCLEOF411 and BlueNrg IDB041A1 board. Unfortunately I use Linux and Idon't want to buy IAR system. First step: I tried to download demo (en.x-...
Posted on May 26, 2016 at 19:43I am using a STM32F0 mcu that run my application. How can i make a bootloader to my mcu appliccation throw the SPWF01SX.1. I was thinking of downloading throw AT+S.HTTPDFSUPDATE but it is not a secure connection. Did a...
Posted on January 29, 2016 at 17:41Hi everybody,this is to inform all of you that a new FW for SPWF01Sx, named 3.5, has just been released.It includes new features...:- AT+S.RMPEER- AT+S.HTTPREQ (thanks to Flow forum user)- AT+S.FSR- AT+S.HTTPDFSWRI...
Posted on June 06, 2016 at 21:12HelloI began to work with this module. It is necessary to make a page, at the entrance to which is: 1) Displays the value of several gpio. 2) it was possible to set the several gpio. What code (command) should I place...
Posted on June 09, 2016 at 08:03Hi,I'am interfacing SPIRIT RF transceiver and using 50 mhz clock crystal.May i know what all changes have to do to work with 50 Mhz clock?May i know MCU states for 50 MHz clock?(in data sheet i have found only for 52 ...
Posted on June 06, 2016 at 13:49Hello! The spectrum of the signal in figure 4 or figure 5 (AN4103. Using the SPIRIT1 transceiver under EN 300 220 at 169 MHz) does not correspond to the real measurements. Quick on and off of the transmitter generates...
Posted on May 31, 2016 at 00:55Hello guys, i'm new in programming stm32f0. I have stm32f091rc and i want to interface uSD using SPI peripheral. first i used stm32cubemx to select the SPI1 peripheral and configured the clock. then i exported the gene...
Posted on May 31, 2016 at 13:08Hello,I bought some X-NUCLEO-IDS01A4 for evaluation of the SPSGRF-868 module. I am not really pleased with the results. So far the best range I could get was 175 m in the same conditions in which I got 150 m with a com...
Posted on May 30, 2016 at 17:58In the SPIRIT1 datasheet it says the SPIRIT1 can be used to provide a clock source for the MCU via a GPIO pin - such that the MCU does not need its own crystal oscillator. However as far as I can tell the default start...
