Previously i tried the peripheral uart and central uart to transfer the data between 2 nordic boards . Now , i want to use the BE33 module foren-USTelligent Community 13Thu, 15 Aug 2024 12:54:11 GMThttps://devzone.nordicsemi.com/thread/498465?ContentTypeID=1Thu, 15 Aug 2024 12:54:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:731b561a-bfbb-4e0c-82f3-9d0f52775ca0Menon<p>Hello,</p> <p>The central_uart sample may not be fully compatible with the BLE BE33 module, even though the module is based on the nRF52833 chipset. Differences in hardware configuration (e.g., pin mapping, peripherals) could cause scanning failures. Ensure that you have correctly configured any board-specific settings in the firmware, particularly pin assignments, clocks, and power management.
