Posted on December 19, 2017 at 11:53I have to use the SPWF01S module to do a remote control by means a smartphone. The SPWF01S module communicates via UART with an electronic board connected to an asynchronous motor. I want to send to the electronic...
Posted on September 05, 2017 at 10:47Hi,I need to have a SPWF01SA module connect to a Wi-Fi router with hidden SSID.The first operation the module tries upon starting is '+WIND:21:WiFi Scanning' which completes with the result '+WIND:35:WiFi Scan Co...
Posted on December 20, 2017 at 18:55I was using a SPWF0SA11 module in my application and it was working fine, when I changed to the production PN, that is SPWF0SA21 I am not able to connect to the module in MiniAP mode. The following message is rece...

Posted on December 18, 2017 at 09:15Hello there!I would like to ask what i'm doing wrong in activating the miniAP with my SPWF04SA. I've read SPWF04SA's datasheet, UM2114, AN4964 and most of ''WiFi Training Hands on SPWF04SA module'' pdf. I have 2-3...
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...
