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,...
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...
