I would like to use TESEO-VIC3D as a replacement receiver in our monitoring products. Ideally this would have exactly the same footprint. What inputs can be left O/C? We use the UART (pins 20 & 21) and 1 PPS (pin 3).
I have received a response on this which mentions pins 1, 6 & 15 as O/C. What about nReset (pin 8) and AntOff (pin 14)?
Resolved! Does the X-NUCLEO-GNSS1A1 come with an antenna?
The databrief for this kit doesn't explicitly state that it comes with an antenna, just "SMA female connector".Can someone confirm if it ships with an antenna? If not, any suggestions for one that fits it?
Serial communication not working on STEVAL-IDB008V1M demo applications
I have an STEVAL-IDB008V1M connected to my Windows 10 PC by USB. I have installed the BlueNRG-2 navigator v.3.2.2. After flashing "Hello, World," a terminal sometimes pops up, and other times I must open one myself. Either way, no text is being print...
The Spirit1 data sheet doesn't have a clear description of how to set the PA_POWER[X] registers for a desired power output level. I would like to set the PA for a 0dBm output - is there a table that relates the register setting to output power level?
I am using the SPSGRF-915 module. Other details: 902-928MHz band, GFSK modulation, 250kBaud, channel filter BW 564kHz, channel spacing 334.2kHz
X-Nucleo-IDB05A1 boards problem
I have a few X-Nucleo-IDB05A1 boards, and when I test them on the X-Cube64 board, some work and some don't. So I checked it, and like the attached picture file, the Trace Code and Bulk ID are different.Trace code XN915011 is fine,11540270 doesn't wor...
Resolved! Issue in sending ADC value over BLE(BlueNRG-LP)
I am having STEVAL-IDB011V1 board. I am developing the battery profile for that i have refer the ADC_Battery_sensor and BLE_sensorDemo example but the code is stuck in below loop. Please let me know what is the issue in firmware. Is the issue is in A...
Resolved! S2-LP P2P example failing after 2 packets received
I'm not sure if the failure is in tx or rx.The full generated project is attachedtested on dual nucleo-f401RE+S2868A1 boardstest protocol: reset both boards, click few times on blue button of a board, and see it just blink twice on the other board.I ...
i am working on a project where i need to enable BLE as client for that i need to understand a few api and function which are listed below, can anyone help me understand them?

Maximum number of services and/or characteristics in BLE GATT
I'm struggling with an issue regarding the number of GATT services, characteristics and descriptors in BlueNRG by STM. I have currently set 6 services and 8 characteristics, minimizing the number of attributes for each service inside maximum_attr_rec...
