Hello,In the datasheet of the s2-lp it is written a frequency range supports by the S2-lp as crystal but nothing is specified for a tcxo, it is the same range ? 24-26 Mhz and 48 - 52 Mhz ? Thanks in advance
Hello everyone,We are using the SPBTLE-1S in order to impelement an SPP protocol. We are using both the Chat and Security example project. Everything works fine except pairing request.When we try to connect to device after a reboot, there's a pairing...
Hi guys,Trying to debug this issue. When I try to set a 128 bit service uuid in my advertising packet, I get 0x42 (invalid param) back from the BLE stack. Here's my call:aci_gap_set_discoverable(ADV_IND, 0, 0, STATIC_RANDOM_ADDR, NO_WHITE_LIST_USE, 8...
Hi everyone,I would like to design my own PCB with BlueNRG. It will be simple board with BlueNRG and H3LIS331DL sensor, very similar to STEVAL-BCN002V1. Schematic of this PCB is clear for me, but I don't have any expieriences of developing RF antenna...
When requesting a scan with duplicates filtered like this:aci_gap_start_general_discovery_proc(ScanInterval, ScanWindow, PUBLIC_ADDR, true);I would like to not receive duplicates during that scan. But when that scan expires (after what is it, 10 or 1...
Hi,when the modules boot I get a string for the FW revision like "140128-caf4b79-SPWF01S". Where can I get the corresponding FW rev like "3.5"?Where can I find the differences between these revisions? Thanks,Robert
Hi All,First of all I apologise for posting this question in the wrong group as I didn't find the appropriate field to choose from the drop down menu list. The kind of response that I get from ST community is very fast and appreciable so I didn't min...
I need a solution ideally based on stm32 + ethernet switch with PTP which has multiple (8 100 Mb fiber/copper ethernet ports). Could someone give me a clue for such a switch which will be suitable for stm32 or ideally recommend me development board ...
I'm using a STWD100NPWY3F watchdog timer, and I can't get it working according to the datasheet. I have the following connections:VCC: 3.3VGND: GNDEN: GNDWDO: 10K pull up to VCCWDI: pull down to GND and toggled to VCCWDO stays low and keeps the MCU i...
I'm using the SPBTLE-RF module controlled with microcontroller STM32F051K8U6. Connection is ok and I can send services, charact and descriptors successfully to my phone app. I'm using STM32_BlueNRG library from ST. I create each service by calling ac...
