Posted on June 11, 2015 at 22:10Hi Gaetano, I'm currently working with the SPIRIT1 on a my own board. An external clock signal is used on XIN coming from my MCU (STM32F4) at 26 MHz. And the central frequency is set to 868.3 MHz. Sometimes, I get an ...
Posted on June 15, 2015 at 15:20Unfortunately the data sheet can be evaluated as a minimum documentation for this chip. Is there any more information available e.g. for the DEVICE_INFO register, what the content is and could be and what it is tellin...
Posted on June 15, 2015 at 12:34Is there a limitation/restriction of of the WEP key lengths in AP mode?Set password to 'test1': AT+S.SCFG=wifi_wep_keys[0],7465737431 AT+S.SCFG=wifi_wep_key_lens,05 This works OK. I can connect fine with WEP authenti...
Posted on June 11, 2015 at 12:22I am wanting to include the STW81200 into a new product design. I am looking for the schematic for the evaluation board that I think exists, but I am not able to find it.The specific information that I am looking for ...
Posted on June 10, 2015 at 08:37Hello, i want to create a connection bettween three SPWF01SA an send data via TCP - socket to any other module. Is there a possibility to create something like that. The firmware is 150410-c2e37a3-SPWF01S. Thanks and ...
Posted on June 07, 2014 at 10:48I can get two BlueNRG boards connecting, one as Peripheral and one as Central, using the code in the BLE_Chat example. In this case the Central has to know in advace the address of the Peripheral. However, when I try...
Posted on June 01, 2015 at 04:19Hello,I've designed BTLE board with BlueNRG and STM32L152. After resetting BlueNRG, voltage at pin12 (VDD1V8) is not stable. It is observed that after every around 1.5 seconds BlueNRG SMPS turns on for a while and goe...
Posted on May 27, 2015 at 13:32Hello, i´m from Germany, therefore please apologize my mediocre english ;). I have some problems with the module SPWF01SA. I want to connect them both to each other. One SPWF01SA is configured in the MiniAP mode. The o...
Posted on April 25, 2015 at 07:20HelloI need to update the firmware (need the 1 command the is in release 3.3)for the above module. I have contacted the local ST agent and have received the required programs and files for the upgrade (via usart)(SPW...
Posted on May 05, 2015 at 04:39Hello there, again,I am trying to query the MCU over WiFi module, using ajax GET requests sent by a browser. The idea is: upon detecting the ''+WIND:56:Insert message to client: '' response, MCU responds appropriately,...
