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...
Posted on April 16, 2015 at 15:36Hi,I'd like to knwow how I can generate a ''Write Command'', opcode = 0x52, in the Attribute Protocol.So far I'm able to send a ''Write Request'', opcode = 0x12, using the Aci_Gatt_Write_Char_Descriptor (HCI = 0xFD21...
Posted on March 27, 2015 at 09:51I use SPWF01SC.11to send data to server (about 6KB every 4 minutes).I split data to 2 packages (3KB each package) then send to server by TCP Socket.But sometime 1 package is lost.Can anyone help me to solve this prob...
Posted on April 12, 2015 at 19:19Is there a way to selectively remove one bonded device from the list of bonded devices? This would be equivalent to the ''Forget this device'' command provided in the iOS Bluetooth settings. I don't think there is su...
Posted on April 10, 2015 at 10:26Hello,I'm trying to get data from a remote sensor.The BTLE is master, role 2.I'm implementing the code right on top of the HCI layer.I'm able to connect to the sensor and retrieve the service and characteristic info,...
