Hello,
I've developed a circuit with Mikroelektronika's nRF T click module. This module uses nRF24L01P but as I see I cannot order it because it is obsolete.
Should...
We plan on use the ST BAL-NRF01D3 balun for a PCB with both an nRF51822 and a nRF51922 on the same PCB separated by about 4 inches.
Should we use the PCB antenna as on...
Hello.
I am very confused with memory layout of nrf51822 BLE examples using SoftDevice stack.
Some examples set IROM1 range from 0x0 to 0x3ffff. (ex, ble_app_advertiseing...
