Hello!
How can I communicate with my nRF24L01+ and nRF51822 at the same time. I can set up same channel, CRC-mode and I don't use ESB. But what about address? How do I set...
I have enabled data ready interrupt bit and also enabled the fifo bit and also enabled gyro_fifo and accel_fifo bits in mpu6050 so that when data ready interrupt occurs the...
I have a nRF51DK. The Softdevice on the board is S110.
I load the ble_app_template from the SDK 8.1 on the chip. It builds with success. Now with the MCP I am able to see...
I'm now using the lastest SDK 8.1.
I found that if I call app_button_enable() after app_button_disable(), app_button_enable() would not function again.
But if I changed...
Hi all,
I read that the nRF51822 comes as a blank chip from the factory, and this means that we have to program the SoftDevice ourself. I am wondering if this is the only...

Hi,
I'm using the softdevice s110.
The power consumption is sometimes a little weird (around 1 mA). I think that the chip is in debug mode.
How can I know if the chip...
Hi,
The datasheet for nRF52 has pin assignments for QFN-48 only at present.
