Posted on March 21, 2017 at 10:35Hi everyone ,For a project I need to make the FOTA work on an STM32L073RZ. I downloaded the package ' FP-SNS-MOTENV1' from ST and tested it on an L476RG with a IDB05A1 together with a IKS01A1, it worked perfectly, I...
Posted on February 04, 2016 at 23:02I have two SP1ML modules, transmitting 11 dBm. If they are really close (1 cm), the RSSI is around -30 dBm, when the distance is 1 m, the RSSI goes down to -90 dBm. It seems that these values are too low. Anyone ...

Posted on March 19, 2017 at 00:30I'd drive an opto-isolator's LED directly from the logic output of ST3232CTR (VCC=5V). I'd set current with a serial resistor (Vcc - R - LED - 3232's output. Output=L to light the LED up). I checked 'DocID7454 Rev 1...
Posted on March 18, 2017 at 20:32I am beginning to experiment with this part but something has me a bit stumped.The eval board says that the transmit filter is configured for a frequency of 150KHz with a sensitivity around 100KHz.However the receive...

Posted on March 16, 2017 at 12:39In order to optimize the consumption in my project i would like to enable the dc-dc converter.The datasheet says ' Optimized results are obtained when the embedded high-efficiency DC-DC step-down converter is used.'D...
Posted on March 16, 2017 at 11:01Hi, i'm working with the BlueNRG-MS evaluation board (x-nucleo-IDB05A1) together with an stm32L073RZ.I'm putting the module in advertising mode with the stm in stop mode. With an 20ms advertising period, i am measuri...
Posted on March 13, 2017 at 11:43Hi guys,I'm using SPWF001 and wanted to write my parser since the host MCU is not STM32 (so I cant use the example). Simple question: If the module is in the middle of +WIND:xx:yyy, and I send an AT Command, is the c...
