nRF52840 SDK Troubleshooting
Budget: ₹600 – ₹1,500 INR
I'm seeking an experienced developer with expertise in Nordic Semiconductor's nRF52840 and the nRF5 SDK, particularly with the S140 SoftDevice.
Project Requirements:
- Read two NTC thermistors using SAADC (P0.30/AIN6 and P0.31/AIN7) every 100 ms.
- Control an NTC enable pin (NTC_EN) on P0.29 to power the NTC circuit.
- Toggle an LED (P0.24) every 200 ms.
- Set a reset pin (P0.13) high after 10 seconds and stop NTC sampling.
- Advertise via BLE
Current Issue:
The ble_stack_init() function fails at sd_softdevice_enable(), returning error code 8194 (0x2002). The SoftDevice is confirmed to be flashed.
Ideal Skills:
- Deep understanding of nRF5 SDK and SoftDevice configurations
- Experience with SAADC and GPIO setups
- BLE advertisement expertise
Please provide insight to resolve this issue.
