Interface and connectivity ICs

Posted on May 30, 2016 at 17:58In the SPIRIT1 datasheet it says the SPIRIT1 can be used to provide a clock source for the MCU via a GPIO pin - such that the MCU does not need its own crystal oscillator. However as far as I can tell the default start up parameters for the SPIRIT1 do not output a clock signal to any of the GPIO pins. So how is the MCU supposed to start up if it is relying on the SPIRIT1 to provide an oscillator signal after a power up. How does this avoid having to have a separate MCU oscillator?

Posted on May 25, 2016 at 14:08 Hello, Please help to clarify the following... I would like to do script to merge image file with required ifr config. To check my tools I have used ''bluenrg_img_converter.exe'' converter provided ST. So I have found that this converter distorts four bytes of the original firmware (b'BLUE' -> b'FFFFFFFF'') because original image realy has 'BLUE' on this place. original image (bluenrg_7_1_e_Mode_2-32MHz-XO32K_4M.img) Could you explain this moment Regards, Andrei Kukenov bluenrg image bluenrg-ms

Posted on May 07, 2016 at 02:51Hello,I'm developing code for the BlueNRG-MS device, in a central role. I'm wondering what API allows me to retrieve the advertising devices name and the packet RSSI?  I've initiated a discovery with aci_gap_start_general_discovery_proc() and receive the  EVT_LE_ADVERTISING_REPORT event, but its not clear how to retrieve the ''Device Name'' and RSSI.Thank you,Brent #ble #rssi #bluenrg-ms #bluenrg

Posted on May 24, 2016 at 10:30Hello everybody,I am designing a small stimulator that needs to wirelessly communicate, for research purposes, and I use the SPBT2632C2A for its low power capabilities and small size. There is a battery embedded but I want it to be as small as possible (for now 90mAh) and to last few weeks.My strategy is the following:I only need few exchange of data every 5 minutes, thus I use a power switch to remove the supply voltage from the device, and I switch it ON only when needed. But it leads to high current consumption during stratup (~30mA_rms during 2s) and then high current consumption during the sppconnect phase (~20mA_rms during 2.5s). Starting up the device every 5 minutes is still far better than keeping the device supplied all of the time (even with the LPO design that I use as advised in the datasheet for low power) because I measured the sleep mode current and it is far from consumming only 70µA as mentionned in the datasheet.Thus:- Would it be some

Posted on April 12, 2016 at 10:56Hello, I want to embedd the BlueNRG-MS firmware in my main application controller flash. Therefore I have to convert the .img firmware file to a binary file. Is there a converter program for this kind of work?

Posted on May 23, 2016 at 11:15I'm working with the X-NUCLEO-IDB05A1 with the BlueNRG-MS on it.I follow the quick start guide (Version 1.4) and on the ''Evaluate BlueNRG using a GUI'' section when starting the BlueNRG GUI (Version 1.9) it asked me to upgrade the BlueNRG firmware.I run the BlueNRG Updater and tried to program the firmware version that come with the BlueNRG DK 1.9.0 under firmware directory (I tried both the 16MHz and the 32MHz) but after a successful (allegedly) flashing at the verify stage it fail in the middle (I tried more then once) with an error message HCITimeoutError.Please advise  #bluenrg-ms

Posted on May 13, 2016 at 13:00Hello sir,I am working on STP04CM05 Driver for msp430. I am struggle with how set the colour and brightness. Send me sample code of it. or possible to send the proper detail of it.waiting for reply... #spi

Posted on May 10, 2016 at 21:22I just purchased a couple modules (SPBT2632C1A) for Blue Tooth 3.I'm trying to familiarize myself with them before they are arrive and there seems to be a lack of information out there.The DS provides some basic info, the UM talks about the AT commands, but there really doesn't seem to be an Users Guide in the sense of how to do anything?Some of the GPIO pins have a predefined functions such as Connection Status Probe / Active Status Probe.........but no where does it explain what those are.Is there another doc I am missing?  Can someone point me to the right place to ask or where I might find the right docs?Thanks

Posted on January 30, 2016 at 00:07Hi, We are encountering the following issue: after some time (minutes), the module is not visible by Android phones anymore, but is still visible by other iPhones or BlueNRG-MS devices. The time after this happens seems highly correlated with the Advertising Interval used (the shorted the interval, the shorted the time after which the device is not seen by Android). The only solutions to see the module on Android after this are: - hardware reset of the BlueNRG-MS module - using 'offloaded' scan on the Android devices Is STMicro aware of such issue and is there any solutions? Thanks, Christian #android #bluenrg #scanning #scanning #bluenrg-ms #bluenrg-ms #bluenrg-ms

Posted on April 29, 2016 at 18:12Does anybody know how to isolate 2 network with the same program (multicast mode) but I want to find just one thing that I could change to separate the network.like network#1  6 devices, each devices have a specific links like  0x22 network#2  6 devices, each devices have a specific links like  0x33etc...

Posted on April 22, 2016 at 17:06Hi Gerry, I need to update the firmware of my devices (not the firmware of the module) over the air. Can you give an example which commands the firmware update with at+s.fwupdate uses and how the firmware update works? Regards, Flow

Posted on March 10, 2016 at 11:33Hello everybody, I have trouble with upload data to external memory with SPWF01SA. which software are you used for create fs image? (*.img).

Posted on April 22, 2016 at 16:07In some conditions i have problems with BlueNRG based device - it fails, don`t enter to low consumption mode, drains the battery. In FW Release Notes i saw a lot of errors and i need some workaround to guarantee reliable work of my device. How can i check operability of the BlueNRG chip from my Application? What command can show me that BlueNRG stack works properly to reboot it if problem occured.

Posted on March 28, 2016 at 09:43Hi, We're using Nucleo-L4 with X-CUBE-BLE1 Expansion SW with lower mode enabled. The 32L4 HSE XTAL input is driven by external oscillator. We would like to disable the external clock during low power mode of 32L4 and enable when 32L4 comes out of low power mode. Is three a way to do this via a GPIO pin of 32L4 ? if so, any guidance will be appreciated. Thanks. #stm32l4-external-hse-x-cube-ble1 #stm32l4-ble-expansion-lpm-stop

Posted on April 15, 2016 at 00:13Hi    I think I found a bug in aci_att_find_information_req which always returns BLE_STATUS_TIMEOUT for me. This function creates a hci_request variable, fills it with zeros, and then sets all fields except ''event''. Then in hci_send_req function, case EVT_CMD_STATUS: gets asserted, and if (r->event != EVT_CMD_STATUS) condition is checked and met (since event == 0). Then, in the next iteration of while loop, I get BLE_STATUS_TIMEOUT.    If I initialize hci_request::event field to EVT_CMD_STATUS, function works, and I successfully got an UUID of handle 0x01. Please note, that every (?) other function with ''aci_gatt_'' prefix located in ''bluenrg_gatt_aci.c'' file has this ''event'' field initialized just like I mentioned, and at the other hand, every function prefixed ''aci_att_'' has not.Please help me verify if this is something wrong with my code, or it's a bug. How do I proceed in the latter case? I've found a

Posted on March 11, 2016 at 12:46Hello, has anybody SP1ML setting so the SP1ML can interact with the NUCLEO P2P demo? From the default SP1ML settings I changed: S10:SYNC_LENGTH=4 S11:SYNC_VALUE=0x1a2635a8 S12:CRC_MODE=1 S28:PAYLOAD_SIZE=25 but I don't receive anything.

Posted on April 12, 2016 at 10:51Hello, I want to update the BlueNRG-MS inside my application. According to AN4491, page 12, you should not erase sector 0 by using aci_updater_erase_sector command. Because sector 0 is the Updater sector. When I update the BlueNRG-MS with the BlueNRG GUI V1.9.0  (Tools -> BlueNRG updater... ) sector 0 is erased. Why? #bluenrg-ms-update-sector

Posted on April 05, 2016 at 18:13I need to send complete (and receive) custom packet through the module SP1ML to cummunicate with another SPIRIT1 board (protocol is fixed). This protocol is based on ''Basic Packet'' (no StAck nor Wmbus) with : 12 bytes preamble 2 bytes Sync Word variable length payload No address sent No Control sent CRC 0x8005 Is it possible to obtain this with the SP1ML module? We used the STEVAL board to communicate without problems. Is it possible to do this with SP1ML with original Fw ? Thank you very much Best Regards Simone #spirit1-sp1ml-dongle #spirit1-sp1ml
