Hi,Before my question, I am new to NFC designs.I want to test my first PCB design, I want it to work like an NTAG, and I want to be able to read and write on my PCB. For this first project, I don't need anything else.My idea is to use the ST25DV04K o...

I'm using the module X-NUCLEO-BNRG2A1 and I uploaded some code to give the BLE module an address, services and characteristics.Now, when I disconnect the module from my NUCLEO-F411RE and connect it to Arduino or I simply power it up, I can't find the...

I want to use the BNRG-MS2P of this module with an Arduino. More specific with a custom PCB with an atmega328p. Any tutorial, Literature I can use. This is a new field for me

Hi,I have a project that needs BLE connection. Right now I have a custom PCB working with a premade BLE module (SH-HC-08), the PCB has an atmega328p. Now is the time to upgrade with a custom BLE chip for creating my own characteristics.For this, I st...

Bluetooth development is a new field for me so I would like to start without any doubt.I'm checking the X-NUCLEO-BNRG2A1 for learning and using BLE in another project.My question is about the register mapping on the datasheet of this board. Why are...

Hello,Just seeing this now. Thank you so much for your answer.A non-shielded discreet coil seems like a good option.If I find a way to design the antenna with traces, do I need something else or I can just connect the trace to the chip? Also, I guess...

This is a new field for me, not sure if I would be able... I can see the device, I created services and characteristics but for some reason, ret is not 0x00. So when I try to upload data I can't because it gets stacked on that if.Any documentation or...

Can I know how did you solve it?

Hi, I also have the same problem, did you solve it? I tried to debug and the value of ret here "ret != BLE_STATUS_SUCCESS" is 0x46 for me. I have no idea why, it should be one of this values:

I see that there are notes like "To use PA1 as SPI_CS with DIO1 mount resistor R70". But I don't know the value, do I have to calculate it? or is there a fixed value somewhere in the manual that I'm not seeing?The purpose is to use a module like the ...
