Posted on June 25, 2015 at 15:29Hi,I'm trying to set up a communication between two SPWF01SA.A is set as the server, B as the client. I wrote a text to send from A to B when the WIND 61 + WIND 60 are detected. If a try to do it just after the WIND 6...
Posted on June 26, 2015 at 09:40I wish to create a bluetooth scatternet. The network consists of 15 nodes (microcontroller and bluetooth module). 3 piconets (maybe more) with 5 nodes . 1-4 nodes are connected to 5 node, 5-9 nodes are connected to th...
Posted on April 28, 2015 at 11:13Hi, I'm testing a solution with Spirit1 + SKY66100-11 for 169MHz transmission. I have a 600mA current consumption with spirit1+sky 66100-11+TCXO. Is it normal? Where Can I found a detailed technical report of current...
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...
