[KarthikKumar]

Hi All,

I'm in process of designing a system which has nRF21540 as the FEM and nRF340 as the chipset, But finding it hard to configure. Can some one help me hoe to connect both and create a new design.

Hi Martin,

Can you suggest me with some accelerometer, magnetometer, gyro meter sensors or combination of all three in a single sensor, that are configurable with nRF5340 development board.

Hi,

When you say nRF5340 development board, do you mean our development kit?

You have several providers of breakout boards with an IMU (Inertial Measurement Unit) with supporting circuitry, for example Adafruit and Sparkfun.

Just do a google search for IMU breakout board.

The nRF5340 should have no issue communicating with any of them.

That being said, if you are going to be programming with zephyr, I might suggest going for either ADXL345, ADXL362, ADXL372, BMA280, BMI270, LIS2DH or MPU9150.

Best regards,

Hi Martin,

I'm using 2 nRF5340 DK boards. All I want to do is,

1. Make one board as peripheral which only advertise that is set up peripheral initially as an advertiser.

2. Make second board as central which shall scan for the peripheral board, Central will scan for connectable devices (i.e. NRF5340 DK boards) and then establish a BLE connection.

3. Connection will be long range coded PHY (128 kbps).

Tried to find the relevant code for this, Can you please help me with some suggestions.

Hello,

Apologies for the delay, I have been away on holiday.

I suggest you create a new ticket for this request as the topic is pretty far removed from the original one.

The ticket will be automatically assigned to a Nordic employee and you should get an answer shortly.

Best regards,

Martin S.
