Posted on May 13, 2015 at 12:42Hi,Which PA configuration parameters should I use in order to get the maximum output power on Spirit1 and which CWC (0 - 1.2 - 2.4 - 3.6 pF) bit field should be set for 868 MHz band?According to the datasheet the max o...
Posted on April 17, 2015 at 22:20In AN4494, Bring up BlueNRG app note, both Chapter 8 and 9 mention thatSend a further command to determine the number of packets sent by the Tx board: HAL_LE_TX_TEST_PACKET_NUMBER What is the LE command above? Where...
Posted on May 05, 2015 at 17:22Hello,the Bluetooth Core Specification defines how the different HCI Command, HCI ACL Data and HCI Events are transported over rs232, USB and 3 wire Uart. There is no definition for SPI and unfortunately I was not able...
Posted on May 08, 2015 at 17:19Hello, Please help me to clarify the following question: my device supports a several modes and I need set special connection parameters for each mode first mode - aci_l2cap_connection_parameter_update_request(handle,...
Posted on May 10, 2015 at 14:52Hello,the very first response I get when communicating with a BlueNRG is the following byte sequence: 0x4, 0xff, 0x3, 0x1, 0x0, 0x1If I get it right, I have to read it like this:0x04 == HCI Event Packet0xff == Event Co...
Posted on May 04, 2015 at 18:06Hello,In Spirit1 datasheet, it states that data is encoded using Viterbi algorithm with R=1/2,K=4.Is there any tool, or source code available with Viterbi decoding(with the specific parameters) so that I can double che...
Posted on April 29, 2015 at 09:26Hi,I'm trying to use custom socket with two SPWF01SA, but I'm having some troubles:-I can't find the documentation, to know how it works exactly-I have a creepy behavior once I try to send data from server to clientI...
Posted on March 04, 2015 at 14:29I have had two boards/chips fail in the same way - one today and one a few weeks ago. Symptoms on both boards are identical: 1) Boards had been working correctly and failed in operation. No obvious damage caused to b...
Posted on April 23, 2015 at 09:58Hi,I have a problem trying to exit data mode upon establishing the connection as the socket server. The problem is that the escape sequence is interpreted as yet another data chunk to be sent to the client. Increasin...
Posted on April 22, 2015 at 17:57Hello, I'm studying the schematics of the spirit1 eval kit at 169MHz (vers. 4). On the PA output filter, L3 is referred as L_TBD_0402. In the BOM, L3 appears as being a ceramic capacitor! Can you confirm this is norm...
