I use S2LP at 433 MHz with proprietary narrowband protocol. Crystal 25 MHz 10 ppm XRCGB25M000F1H02R0 from Murata; capacitors 18 pF. Devices operate OK if ambient temperature is positive. When I put them into freezer they stop responding to the base ...
Hello, is there a way to use Teseo Suite with NUCLEO-L476RG. The "X-CUBE-GNSS" software only provides an app for NUCLEO-F401RE, called "Virtual_COM_Port_UART". Thanks
The STUSB4500 and STUSB4500L are similar in nature, however the NVM config for the STUSB4500 is not compatible with the STUSB4500L. Is there a way to identify the part number via the I2C bus? The Device ID Register returns 0x9C for both the STUSB45...
Hello,I tried to upgrade STSW-STUSB002 V1.09 (early 2019) which works well with STUSB4500 chips, but doesn't with 4500L ones! Not same register mapping?..I installed STSW-STUSB002 V1.11 (early 2020) but no more "SINK PARAMETERS" on the GUI.Do I miss ...
Hello there,What's the total range of BlueNRG-M2SA? I read in this forum that is 33 meters, it's correct? My application needs something about 500 meters. Does possible reach it with BlueNRG-M2SA (or BlueNRG-2)?Best Regards,Leonardo
Hello I'm in the development of the bluetooth communication between two bluenrg-2n devices. The bluenrg-2n are connected with stm32f405 through SPI. I'm not new in stm development but new in bluetooth communication. I've already done the init process...
Can I interface these two boards?Can I program X-NUCLEO-BNRG2A1 without a Nucleo board? Is the X-NUCLEO-BNRG2A1 programmed via the host Nucleo board?I'd like to not purchase the much more costly STEVAL-IDB008V2.On the other hand, I'm just starting wi...
Hello,I am currently working on a project that requires 6loWPAN over Bluetooth communication. I have a STEVAL-STWINKT1B development board and it comes with a BlueNRG-M2 BLE module. I have checked the BLE examples and the documentation provided by ST,...
I have configured the GPIO for I2C1(Alternate function 4) and enabled the Clock for I2C1. After that I am trying to enable the ACK. but not able to enable that.. Also tried for I2C2 and I2C3 facing the same issue.//enable the clock for the I2C periph...
What are the power levels for the different settings when calling aci_hal_set_tx_power_level()? All I can find for sure is a max power level of +8 dBm in the datasheet. Other tables I find in the BlueNRG-1_2 DK documentation give conflicting answer...
