when I try to read software version (before gap or gatt initalization) using aci_hal_get_firmware_details(), it ends up to this and always fail to get the data correctly

I using BlueNRG M2 as a network co-processor and have configured my project with STM32 CUBEMX which uses X-CUBE-BLE2. It is a non RTOS based project and is working well.Now, I want to use RTOS (FreeRTOS) with the BLE stack. Is there any example which I can refer to or any docs on how to use it?

str485 differential output is not as expected , we have followed datasheet to design pcb yet only one signal (non inverted) is showing up as expected in logic anlyser (see attachment)attaching pcb design for your reference.Should the outputs A and B have 2 resistors 63ohms each with a centertap capacitor connecting to gnd as used in some evaluation board?Kindly provide a solution Thank youupdate: added 20k pullup on A and 20k pulldown on B output line as per failsafe configuration .

I am trying to communicate with VN9D30Q100F slave from TI SOC as a Master.First command i am sending as 0xC2 to read product code 1 as a 58h. But in response i am able to get only Global status byte 0x41 as first byte and rest two bytes are 0. Second command if i send same i see that i am getting 0x01 as a global status byte but rest of the two bytes are 0. Tried few other commands also like 0xC3, 0xC4.I am able to get only GSB in response correctly which indicates that Slave is in fail safe mode. But rest of the two bytes are not correct.Can anybody help me with this issue to know what could be wrong here.Thank you

Dear Community,I have a setup of 2x SPIRIT transmitters. The CSMA is disabled. Both are configured for continuous TX. However, I observe the following:1) The SPIRIT that boots initially starts transmitting without any issues2) The second SPIRIT (that boots after the first one) never manages to start a transmission.Could you explain what is happening and why?BTW, I somehow find the SPIRIT1 support really scarce in the community... Thank you!

Spirit1 normally makes reset, then, after any command of RX, TX or LOCKRX, LOCKTX it is always goes in error state Status registers are steady 0x02 and 0x27 and no further commands are executed, excluding reset and sleep. This is unknown error, I don't know what to do? Registers FA=0x02 and 0xFB=0x40. They also are not in table of possible values, so I'm completely lost. May be here are initialization problems, I have not any initialization sequence hints or examples. All other registers are as they should be after reset. What to do?

We found in a LOT # T2N15KQN0001, which includes 3000 BlueNRG chips, that 300 (10%) are paired after a very long time, (15-20 seconds) while all the other paired after 5 seconds only.When changing the CPU, the problem is fixed - the CPU environment is OK. All other featured (after pairing) are operating as usual.Please Advise - thank you!!

I am using BlueNRG M2 and would like to increase the MTU size from default 23 to 100 bytes.After reading PM0257 programming manual, I tried calling aci_gatt_exchange_config function which sometimes returns BLE_STATUS_SUCCESS and sometimes throws BLE_STATUS_NOT_ALLOWED error.I am unable to find the reason why it throws BLE_STATUS_NOT_ALLOWED error. What could be the cause for the same?Following is my code implementationstatic void User_Process(void) { tBleStatus status;   if (connected && !mtu_exchange_called) { mtu_exchange_called = true;   status = aci_gatt_exchange_config(connection_handle); if (status != BLE_STATUS_SUCCESS) { // Handle error } } }

I have configured a GPIO as input to control the RX or TX state, is there a minimum time above the high level threshold to respect or exceed the VDD/2+0,3 voltage is sufficient ?Thank you,Andy Rochette.

I have BLUENRG-M2SA BLE module that I am trying to interface with STM32l496 IC.I generated the code through STM32CubeMX using X-CUBE-BLE2 v3.3.0 selecting HCL_TL Basic and HCL_TL_INTERFACE UserBoard.The code gets compiled and when I try to flash and debug, hci_reset function returns BLE_STATUS_TIMEOUT error.Following are connectionsSTM32 BLUENRGM2SA SPI_MISO DIO2 SPI_MOSI DIO3 SPI_CLK DIO0 GPIO_OUT DIO11 // CS GPIO_OUT RESETI read DT0137 Design tip manual to make the following changes when using BLUENRG-M2SA development board:HS_SPEED_XTAL=HS_SPEED_XTAL_32MHZLS_SOURCE=LS_SOURCE_EXTERNAL_32KHZSMPS_INDUCTOR=SMPS_INDUCTOR_10uHThe macros seems to be renamed as following:HS_SPEED_XTAL=HS_CRYSTAL_32MHZLS_SOURCE=LS_SOURCE_32KHZSMPS_INDUCTOR=SMSP_10uHAbove changes were made but still it throws the same error.Do we need to make any additional changes to use BLUENRG-M2SA in a network co-processor mode? I directly opened the packing, soldered on custom board and using it.What could be the re

Can we connect D1+ to DN and D1- to DP (same for the connector (D1+CON to USB_D_N))

Hi all, i got to know a bug/problem/issue in SPI communication. one of my colleague is working on designing controller(complete SDK), he has an issue, the issue is, whenever he writes the data from master it writes properly, but when trying to read the dta, he is not able to read it in one run, for second run data can be read, but for first run its taking some garbage value. if nay one has faced such issue? any suggestions for what might be the problem for this,? clock phase and clock polarity are same no change in that.

What is the lowest power cameras available? MIPI or other interface.Super crystal clear image is not important, but something in range of 1 megapixel or more required.Most i've searched are in order of half watt. Which is a lot.Can anyone point me to maybe some article to get the knowledge on that subject?

Hi,We are using the 54VCXH163245 in one of our designs. The chip has 3.3 V VCCA and 1.8 V VCCB. According to datasheet, VCCB must be powered before VCCA at startup. Have you done measurements on the current consumption of the device when VCCA is set and there is no VCCB ? We observe a high power consumption (about 2 A) on the 3.3 V until the 1.8 V is risen (6 ms after). Can this chip be reponsible for this ? Many thanks in advance for your help.

Does BlueNRG-2 allow bluetooth audio mesh network, in which a source (phone) connects to one end point, which acts as master towards another endpoint and this one being slave.

Hello,I am writing some BLE firmware using the BlueNRG-M0A model on a Nucleo board to try and develop an understanding. To try and build an understanding, I am creating multiple services and characteristics with different functions (read only, read/write, etc.) and I am noticing a problem when I try to use the ST BLE Toolbox to verify the proper setup, I notice that certain UUIDs cause previously created characteristics to be overwritten. For example, when I use the following UUIDs, all only the last characteristic (E909930B-39D7-0000-8FE12A48A02B36E6) is visible in the ST BLE Toolbox.Characteristic UUIDs:E909900B-39D7-0000-8FE12A48A02B36E6E909910B-39D7-0000-8FE12A48A02B36E6E909920B-39D7-0000-8FE12A48A02B36E6E909930B-39D7-0000-8FE12A48A02B36E6Then, when I use the following UUIDs, all the characteristics are visible in the ST BLE Toolbox.Characteristic UUIDs:E909900B-39D7-0000-8FE12A48A02B36E6E919900B-39D7-0000-8FE12A48A02B36E6E929900B-39D7-0000-8FE12A48A02B36E6E939900B-39D7-0000-8FE12A

HW: ​BlueNRG-1 development platforms (order code: STEVAL-IDB007V1)GUI: BlueNRG4.4 I followed um2071-bluenrg1-bluenrg2-development-kits-stmicroelectronics to try to upgrade the firmware. the LED2 is flashing.....buf upgraded fail. Is there any wrong or missing about my opreation? thanks!

Hello guysHave ST an Official or Unofficial firmware for BlueNRG-LP that enables control it over AT commands?Regards,Leonardo Trinta

I need a DTM firmware for BlueNRG2 which works wirelessly with the equipment shown in the image. I wonder if ST provides their customers with such a firmware? thanks,

We have connected the BlueNRG-232N to a host processor using the UART.The BlueNRG-232N should function only as a BLE interface, as a way for the host processor to communicate with a smart phone.But I'm stuck on how to do this, do I need to load the BlueNRG-232N with a c-program ?Maybe I misunderstood, but I read that the BleuNRG-232N was pre-programmed ?
