Posted on May 03, 2018 at 18:56The situationWe are trying to use the SPWF04SA WiFi module to readout and control values on microcontrollers. As a test, we are using a Teensy 3.2 microcontroller and send/receive messages using the MQTT-client on the ...
Posted on May 02, 2018 at 12:36I am posting data up to a server using HTTP post, the module sends the data in chunked mode. It is a relatively short packet, so is sent in one transfer. However the module does not end the transfer by sending a last c...
Posted on April 26, 2018 at 08:06How many NET keys & APP keys, provisioner could attached with &sharpBlueNRG_Mesh NODE ?I need at least 2 NET keys & 2 APP keys as per Bluetooth SIG specification.One pair (APP + NET ) will be for Admin of Network & o...
Posted on January 29, 2018 at 13:55Hello,We see a Factory Reset:1 When power cycling the SPWF04S. In about 80% of the times.It is setup as a mini AP when the power cycle is done. Since the host is running lower UART speed than the SPWF04S it complic...
Posted on April 30, 2018 at 16:11Hello, I would like to share one complication with editing files on SPWF04.My SPWF04SA is connected via SPI to MCU (STM32F407). SPWF04 webpage should be dynamically updated with data from MCU.My solution is MCU gets...
Posted on April 26, 2018 at 05:28We have started proto-typing with BlueNRG2 reference board. However, I met a following problem.If someone have had same experience or solution, please share with us.Problem:- ROM image as a example of HID/HOGP provid...
Posted on April 27, 2018 at 15:58We are using SPWF01SC.11 in the design and FW version is 3.5.3 (170111-665d284). When we send the command 'AT+S.SCFG=wifi_tx_power,12', We are not consistently getting positive response from the SPWF01 module. Please...
Posted on April 27, 2018 at 14:03Hello,I am using the SPWF01 (FW 170111) WiFi module together with a STM32 host controller to build a MiniAP with TCP socket server. Data is transfered in DataMode.In principle it's working fine, but:1. Some user can'...
Posted on February 28, 2016 at 21:46I've been introduced to SPWF01S WiFi during Embedded World 2016 exhibition at Nuremberg a few days ago.I have an application that requires 8 or more server sockets in AP mode. SSL sockets would be a plus.The guy ...
Posted on March 20, 2018 at 20:28Hello everyone,Based on the evaluation board of SPBTLE-1S, we are going to make a board with SPBTLE-1S. So the question is:Would be able to program the module (the internal BlueNRG) only with the below signals? We ch...
