If we need to join the onoff_light (ZC) then we would need to use some ZED project for the CC2340R5 (likely onoff_switch). I have &quot;tested&quot; the communication through two ways: -Using the logging feature in the local project - - like: Log_printf(LogModule_Zigbee_App, Log_INFO, &quot;ZB_ZDO_SIGNAL_SKIP_STARTUP: boot, not started yet&quot;); -Wireshark to monitor data over the air Thanks, Alex Fhttps://e2e.ti.com/support/wireless-connectivity/zigbee-thread-group/zigbee-and-thread/f/zigbee-thread-forum/1695108/cc2340r5-does-the-zboss-protocol-stack-provide-rf-communication-testing-functionality-or-how-can-802-15-4-rf-communication-testing-be-integrated-into-the-zboss-project/6530921Thu, 05 Nov 2026 01:38:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:36169df9-b5a7-45f0-aec0-044e001481d7Aries LordCan rfPacketRx/rfPacketTx example join into a ZBOSS project? rfPacketRx/rfPacketTx example join into onoff_light example.https://e2e.ti.com/support/wireless-connectivity/zigbee-thread-group/zigbee-and-thread/f/zigbee-thread-forum/1695108/cc2340r5-does-the-zboss-protocol-stack-provide-rf-communication-testing-functionality-or-how-can-802-15-4-rf-communication-testing-be-integrated-into-the-zboss-project/6530488Wed, 04 Nov 2026 17:22:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:05731c6b-6bc1-4136-aa84-2fe7f12fd26fAlex FagerHello Aries Lord, Can you expand on what you would like to test?

There is one documented RF-related mechanism that stops this oscillator, and it involves the device&#39;s PA, not an external transmitter. What is documented The CC2652P7 errata describe a single oscillator-stoppage condition: at temperatures below −20 &#176;C, high-power PA operation can affect the 32-kHz crystal oscillator through RF load-impedance mismatch; the oscillator may stop and reset the device when the clock-loss detector is enabled 1 . Specified mitigations for that condition: - Follow the reference RF balun and matching-network component values and layout, with balun amplitude and phase balance better than 1 dB and 6 degrees 1 - Avoid antenna impedances outside VSWR 2:1 in all operating scenarios 1 - Limit RF output power to 17 dBm maximum for non-reference PCB designs or where antenna impedance can vary 1 - Enable clock-loss detection ( OSC_DIG:CTL0.CLK_LOSS_EN = 1 ) so the device resets if the oscillator stops 1 Note the relevance to your case: your office is at room temperature, so the errata condition itself does not apply. However, the mechanism is load-impedance mismatch at the antenna coupling into the oscillator . A strong external field incident on your antenna changes the RF environment the PA sees, which is the same physical domain — but this extrapolation is not documented by TI. Knowledge gap — flagged explicitly The retrieved material contains no RF-immunity specification, susceptibility threshold, injection-pulling data, or oscillator-specific RF-coupling limit for the CC2652P7 LF crystal. The product parametric lists only 32.8 kHz LF clock frequency, 350 ppm frequency-error tolerance, 50 ppm/&#176;C temperature coefficient, and 600 ppm calibrated RTC variation — nothing on interference susceptibility 2 . E2E threads involving CC2652P7 RF problems attributed failures to matching-network values, PCB layout, or incorrect PA components, never to LF-oscillator coupling 3 . So your location-correlated symptom cannot be confirmed or ruled out from existing documentation. It requires isolation testing on your board. Isolation steps Confirm the oscillator is actually the failing element. Poll XOSCLFRIS , which indicates XOSC_LF has been frequency-qualified and stays asserted until the oscillator is disabled 4 . Log it at the office. If it never deasserts, your timer fault lies elsewhere in the software/protocol stack, not in the crystal. Switch the LF source to the internal RC oscillator. The low-frequency clock can use the internal 32-kHz RC oscillator, an external clock on a DIO, or the crystal 5 . If the timer fault persists on RCOSC_LF, the crystal is exonerated. Verify the crystal meets spec — 32.768 kHz across X32K_Q1 (pin 8) and X32K_Q2 (pin 9), ESR 30 kΩ typical / 100 kΩ maximum, load capacitance 6–12 pF with 7 pF typical on TI reference designs 6 7 . A high-ESR crystal or load-cap mismatch leaves minimal startup margin, which makes marginal designs fail under any added stress. Review RF layout against the reference design. The datasheet directs designers to the CC13xx/CC26xx Hardware Configuration and PCB Design Considerations application report, emphasizing close adherence to reference component placement, decoupling, DC/DC layout, and ground connections 8 . Verify your antenna VSWR in the deployed enclosure. Reproduce deliberately. The only way to confirm external-field causality is a conducted or radiated immunity test with the symptom correlated against XOSCLFRIS .

Generally, when a pin is floating and it is not assigned a state then there is no way to determine what state it will be in. This will lead to varried results like you have seen here.

But fortunately I`ve been able to locate the issue. We have external memory connected through SPI - and the main problem was the MISO/POCI pin. So generally our fix was a one-liner - adding internal pulldown to MISO/POCI pin. After this change we can measure very similar current on every device on 3V supply voltage. Still not sure why it doesn&#39;t work the same on every MCU. Any insight on that ?

As a result, the timer stops working, and the scheduled timeout never occurs. However, when I take the device home, approximately 5 km away, the external low-frequency crystal oscillator resumes normal operation, and the timer works correctly again.

If it is on a custom board then I would recommend putting the device on a launch pad to check if this is a hardware PCB issue. I also suggest that you try putting the device in standby mode while running a BLE example from our SDK. If there is not high current draw while it is running BLE then there is probably a software issue related to Zigbee. I suggest modifying the simple_peripheral example from the SDK to not blink the LED and it will then send the device into standby mode. Let us know if it is determined to be an issue with the CC2652R7 device. Best, Katy
