I am using ADS1298 AFE in my application which is interfaced to ARM micro-controller over SPI. I have interfaced CC2541 BLE to micro-controller over same SPI lines. Before BLE is programmed I observe DRDY pin on CRO and it shows correct behavior. I have set 256 sample per second rate so accordingly DRDY output pulse every 4 ms and I am able to read the data from AFE. But When I flash BLE program in CC2541 chip then DRDY goes high permanently and never comes down. Pl. suggest me some guideline to solve this problem.
