Unfortunately this means that the PCB antenna design could be suboptimal which is resulting in poorer performance than expected. Regards, Ryanhttps://e2e.ti.com/support/wireless-connectivity/zigbee-thread-group/zigbee-and-thread/f/zigbee-thread-forum/1647540/cc2652r-zigbee-range-issue/6352496Wed, 20 May 2026 11:43:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:24872d93-503c-49df-9dca-c8c5f2f6f32eZCHi Srinivas, I took a quick look at your PCB layout in the previous thread you linked. My initial impression is that the TI reference design layout hasn&#39;t been as closely followed as we would recommend. I would strongly advise submitting your design files for review using 2.4 GHz Design Review Submission: https://www.ti.com/tool/SIMPLELINK-2-4GHZ-DESIGN-REVIEWS You can then get more targeted feedback and implement the changes. I&#39;m not sure if that has been done yet, but should be as the first step if it hasn&#39;t.

Further device selection depends on whether a module is needed (coming later this year), output power (PA enabled devices for up to +20 dBm instead of +8 or +10 dBm maximum on non-PA devices), flash memory requirements (CC2340R5 has 512 kB whereas the CC2755x10 is , RAM restrictions (CC2340R5 is 36/64 kB whereas CC2755x10 is 162 kB), etc. You can reference the Datasheet and Technical Reference Manual (TRM) of each device for more information.

We are exploring suitable Zigbee chip or module solutions and would like to request your support and proposal. Below are our initial requirements: A Zigbee chip or module compatible with integration into an electronic door lock system Latest available Zigbee version and supported protocols Electrical and mechanical specifications, including interface, pinout, power consumption, and antenna options Security features, OTA capability, and certification compliance Recommended development tools, SDKs, and documentation Estimated pricing for samples and bulk orders Lead time for samples and mass production Technical support availability during development and coordination with our factory engineering team We would appreciate it if you could provide your recommended solution along with the full technical specifications, datasheets, and commercial details. Our team is ready to coordinate further to ensure compatibility with our existing lock hardware. Thank you in advance for your assistance. We look forward to your proposal and to the possibility of working together.LP-EM-CC2745R10-Q1CC2538-CC2592EMKLP-EM-CC2340R5CC2755R10CC2755P10CC2340R5https://e2e.ti.com/support/wireless-connectivity/zigbee-thread-group/zigbee-and-thread/f/zigbee-thread-forum/1641416/cc2755r10-radio-frequency-plan/6329345Thu, 30 Apr 2026 06:53:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:0c432ca0-2c27-4f80-8293-10d7a8ca5231Flemming Noerskov LarsenHello Alex Reading the How to Certify Your Bluetooth Product (Rev.

Under normal conditions, the current consumption is around a dozen milliamps or so, but when the abnormality occurs, the current draw can reach over 400 mA. We tried adding a 10K pull-down resistor to the corresponding pin, but it was ineffective. The only solution that worked was adding a 10nF ceramic capacitor between P0_2 and GND.
