Is there a sniffer that can just be run over SPI without a USB host controller

[GerryB]

I need a module that I can poll over SPI from my host MCU an output of a FIFO buffer of incoming packets (MAC address and RSSI) on channel 37 Bluetooth. Or a module where I can set the channel via SPI. Should be a surface mount device with no thru-hole pins. Or I can build around a chip.

Hello,

Is it important that you only scan on channel 37? The reason that I ask this is because that the scanning function in the softdevice only supports scanning on channels 37, 38 and 39, and not only one of them. If you want this, you will have to do proprietary radio scanning.

 

The SPI part is not a problem, we have an SPI example in our SDK under: SDK\examples\peripheral\spi

 

BR,

I could live with the scanning of all 3, but ultimately want one focused on 37, and one focused on 38, and finally a third hardware chip on 39.  So far I like the Nordic platform more than ti, mostly because I dont need IAR.  I am a bit hesitant coding assembly language for a 32-bit controller (Cortex M0 ?), but nRF51 seems to have good documentation on registry locations etc.  When you say "proprietary radio scanning" I assume you mean setting the Table 111: Frequency as described on page 93 of the nRF51 ref manual ?

Or to be more specific , to set address 0x40001508 (frequency) to the proper MHz (2400 MHz plus the value at this address, in increments of 1 MHz)

Can you tell me which SDK file path you're referring?  Ive been through both (nRF5 SDK Zip File - works with S132 v3 and S130 v2 12.3.0)  and  (nRF5-SDK-zip nRF5 SDK Zip File - works with S112 v6.0.0, S132 v6.0.0, S140 v6.0.0, and S212 v5.0.x )  but could not find the directory SDK\examples\peripheral\
