Posted on June 20, 2017 at 11:26Hello,we are designing an RF interface for the ISM 868-870 MHz band.We are attracted to the S2-LP transceiver mainly because it drains only 10 mA at 10 dBm RF output powerI got a couple of questions about the S2-LP tr...
Posted on December 14, 2017 at 15:10Hi,We are trying to communicate with SPWF04S over SPI interface. We can send commands to set or get wifi configurations.Problem just happens when we try to send 'AT+S.WIFI=0'. In SPI mode, this command will be con...
Posted on December 15, 2017 at 10:05Hello,I am trying to develop a Sigfox application with the S2-LP transceiver.I bought the STEVAL-FKI868V1 evaluation kit and I downloaded the STSW-S2LP-SFX-DK software.Everything works well with the kit, but now I...
Posted on December 01, 2017 at 06:26I am using aci_gatt_update_char_value() on a BlueNRG-MS to send notifications to a master device. The first number of times this function is called it returns BLE_STATUS_SUCCESS but then it returns BLE_STATUS_INSU...

Posted on December 12, 2017 at 14:19Is $SUBJECT available ?Given the absence of detailed SPI protocol descriptions (and the problems I face), I'd love to read the source.I'd like to implement a custom RTOS task on the module. I don't need microphyth...
Posted on December 13, 2017 at 09:51Hi All,We are using BLENRG-1 for TAG, the BLENRG-1 act as slave and connected to another MCU, The BLENRG-1 containt just the BLE-STACK, i have few questions regards to BLUENRG-1 and mass production:1- Did the BLUN...
Posted on November 08, 2017 at 17:45Hello,I have differents slave devices bonded to a master device, I would like to remove a unique address currently bonded to that master device, is it possible to do it without using the aci_gap_clear_security_db(...
Posted on December 08, 2017 at 12:02Hi,using newest fw and x-cube 3.1.0 in an UDP ping-pong application I can get no more than about 3kBytes/s.I guess the reason is the 'Socket Query for SPI interface may stall ...' 'known limitation' mentioned in t...
