NRF51822 OR NRF52832 AS A SLAVE DEVICE

[vipin]

Dear sir,

Can we use NRF51822 OR NRF52832 as a slave device .As our controller is STM32F407ZET6 and we did not want to change any firmware from our previous version except the RSSI.

can you please inform us weather can we use NRF51822 OR NRF52832 as a slave so that we need not to load any driver for the NORDIC chip and all nrf Registers will accessible by the STM controller.

Please suggest..

Regards, Vipin

You want to have nrf24-like registers from nRF52 available directly from STM? I don't think it is possible.

First, registers on nrf24 are completely different than nRF52, second, you cannot access any registeres on nRF52 DIRECTLY by SPI.

You can try writing some SPI-based "emulation" that would simulate nrf24 behavior on nRF52, but i think it is completely not worth the work, and it is just better to change firmware of STM32 and use serialization driver (if you want to have BLE) to control nRF52. Or just change STM32 to nRF52...

Dear sir, We need this as because we are using 2 RF channel data on single controller to send to another card,

It will be difficult to use to separate chipset of NRF51 or NRF52 working as a controller to send data to other board as this may lead to another issue .so if there is any ic with default drivers that we can directly use to collect the data and process it with our controller will be quiet helpful for us.

Please suggest

Hi Vipin,

We have some serialization libraries for the nRF51 in our SDK for both UART and SPI. You can run the application on external MCU and use the nRF51 as connectivity chip. Please have a look here
