Bluetooth v4.2 included an ability for attributes to be greater than 20 bytes of payload data long. Is there anything in the nrf51822 hardware that would prevent this from...
Hi,
Does anyone know the maximum baud rate of the nrf24l01+? I am trying to talk to it through SPI but observe that when I increase SPI speed I read incorrect values. Does...
Recently I was attempting to use the nrf51822 SDK's app_uart module's APP_UART_FLOW_CONTROL_LOW_POWER mode (currently using APP_UART_FLOW_CONTROL_ENABLED ). I noticed that...
Hello,
I would like to send some data i read over I2C. But the I2C and BLE Stack should not run at once, is it possible to check the state of the BLE stack?
The core specification v4.0 vol 3 part C section 3.2.2.3 "Bluetooth Device Name -- Representation" states that the device name can be up to 248 bytes. I've confirmed that...
Dears:
I know there are three modes as below :
(1) internal LDO regulator
(2) 1.8 V low voltage mode
(3) internal DC/DC converter
So, I have some questions as below...
