Posted on July 11, 2014 at 11:28HI, I'm developing a device based on the BlueNRG. In my project I need to work with multiple slaves, ie the BlueNRF is in the CENTRAL mode. I use bluenrg_6_3 image (MODE 3)Now I have the following problem:1. if I use ...
Posted on September 17, 2014 at 13:24Hello, I'm wondering if there is some possibility that BlueNRG (which has established connection - slave role) will produce non-connectable advertising (same as device C at Bluetooth 4.0 core spec. Vol1, Part A, ...
Posted on October 28, 2014 at 11:21Hi,I have custom designed board with CR95 + STM32F103. It almost copied from MB1054A demo board. I use libraries and API form ST: lib_CR95HF.c, lib_iso14443A.c and drv_CR95HF.cI wrote small programm that initialize...
Posted on November 13, 2014 at 21:46Back in version 140128, the documentation for dynamic web pages for the output demo (sending messages to the micro over the serial port) used test.cgi to shoot values out the serial port.Recently I updated to 1408...
Posted on October 16, 2014 at 09:07I started up on SPIRIT1 dk, development kit. I read on net that 6lowpan/contiki is ported on to stm32l+SPIRIT1, and ST promotes that. But however I'm not able to find downloadable contiki spirit port anywhere. Cou...
Posted on October 15, 2014 at 23:36Is it possible / practical to reprogram a Spirit1 USB Dongle (STEVAL-IDS001V5) to operate within the band 921-929MHz (which is available for general use at 1W in New Zealand)? If so what would be the approach, hard...
Posted on October 08, 2014 at 15:52Hello DevelopersIn document “Spirit1_presentation_ST_Days.pdf“ and “Spirit1_datasheet.pdf�? transition time between different states /operating modes are calculated using 26 MHz and 52 MHz Xtal. So, please inform m...
Posted on September 24, 2014 at 13:18Hello How many packets can the BlueNRG send in a single connection event? I need this information to estimate the possible throughput. Thanks!
Posted on August 02, 2014 at 18:07Hello,after connection establishment BLE spec suggests/allows to change connection parameters based on the actual requirement. E.g. connect with slow interval for normal operation, but after some time when needed fo...
Posted on August 02, 2014 at 17:45Hello,there is one parameter in aci_gatt_add_serv() which needs clarification: max_attr_recordsLooking at the documentation and the sample code (the comment there suggest that even the st programer of the sample cod...
