Is that possible to add Mesh to an existing project ?

So, i test BLE and BLE Mesh on a BlueNRG-2 with apps from ST and it's working well. Now, i want to add Mesh to an existing project that work with BLE. Is that possible ? Sincerely GF

hi, We have RS-485 with ST1480. we need 1kV surge protection. We use TVS and serie resistor in front-end. surge pulse higher then absolute rating. Will chip survive this. regards

When surge will be done the lab, they will surge at 1kV so every TVS can get (1000-31)/80 = 12A in theory. As 1A gives already 19V this is also above absolute ratings, 12A will be close to 28V.absolute rating inpût is 14V. for a quality product: can ...

S2LP CLI problems

I am using a STEVAL-FKI433V2 to try to create a packet sniffer. The standard on-board software is clearly capable of working with the supplied Python GUI to configure the radio and listen for packets. I have been attempting to send commands to the de...

USB-PD Core Stack

Document UM2552 does not mention Fast Role Swap, Does STM USB-PD core stack library support FRS? If it does, anyone have more information about FRS in USB-PD core stack?Thanks

I am looking for ADPCM library for Bluenrg-M2 module. Can someone please guide me for the BLE libraries of Bluenrg-M2 module

BlueNRG-1 high consumption in low power mode

Hi!I'm using BlueNRG-1 to beacon some messages.I tested a simple scenarious:100ms advertising messagesAdvertising with no connections allowed (ADV_NONCONN_IND)disable all GPIOsdisable debug printf and UARTI use the BLE_BEACON sample code with SDK 3.2...

What throughput should I expect for two BlueNRG-2's in SPI_DTM mode with DLE feature enabled?

I have ported the BLE_Throughput_EXT example for two MCU/BlueNRG2(DTM) setups to communicate with each other. I was getting around 34 kbps. When I implemented this example on a single setup and configured it to send out Notifications when connected ...

Why does BLE_OTA_ServiceManager example in BlueNRG-1_2 DK 3.2.0 implement application level CRC?

Doesn't the BLE specification already include a 3-byte link layer CRC field? Is this just for extra precaution when dealing with delicate firmware data?

Any difference between X-NUCLEO-IDW01M1 and X-NUCLEO-IDW04A1 ?

Right at the moment I have 2 X-NUCELO WIFI expansion board, X-NUCLEO-IDW01M1 & X-NUCLEO-IDW04A1. I am pretty confused, which one to use for an NUCLEO-144 STM32-Cortex M4 ?Is there any difference between the 2 boards?Which one is easy to manipulate?t...

In the MFT routine provided by bluenrg-2 Navigator, MFT1 is timed at 500ms, the interrupt function LED lamp flips, and the flip cycle read by oscilloscope is 250ms. Why? Expect an answer.
