We designed a board using BlueNRG-2 and we uploaded the GPIO demo code available in BlueNRG-2 navigator (to toggle DIO14) to the board using the BlueNRG-ST- Link utility. The board didn't detected with high Frequency(.9MHz-4Mhz) so we changed the SWD...
Hi,I'm going to use SPBTLE-1s for comunication between PC and uController over bluetooth (SPI->SPBTLE) in a new project.Is it possible using SPBTLE-1S without programming (buy and mount it) or is it necessary to program it before ? Do I need to have ...
I am need to change the authentication requirements on the fly based on who is connecting to the device.
SCL mode is Fast Mode but i.e whoes speed is 400KHz. but when i see in logic analyzer its shows 350-360KHz. Why its fluctute .
I am trying to find out how to set up this as a master processor. I am trying to find out how to program it. Is an Stlink/V2 acceptable to flash it. I am not seeing a pinout on BLUENRG-M2SA for SWDIO and SWCLK. It is not supported by Cubemx ...
Hi guys,I need to add the Device Information (0x180A) service in the advertising phase.I tried to do that in aci_gap_set_discoverable function, but ever fails with error 0x42 (invalid parameter). Whitout service uuid list, works ok.So, I tried with a...
I am working on a project using the I-Cube-LRWAN software package, precisely the AT_SLAVE project form the b-l072z-lrwan1. I want to upload the AT_SLAVE project on a L0 MCU interfacing the cmwx1zzabz-091 LoRa module. Then I have an other MCU (L4 MCU)...
i am working on a stm32f746 board and i am using a hc-05 bluetooth module. i didn't know how to receive the image file and store it in the sd card. any help please ?
