LTE/BLE Gateway Issue

[m.abdelgyd]

I'm trying to run LTE/BLE Gateway sample on nRF9160DK , i followed all the instruction in the sample instructions.

The Jlink RTT for nRF52840 and LTE-Link Monitor logs are as follow :

especially the error :

I'm not sure how to fix this issue ?!

Could you test something? Try to set CONFIG_BT_WAIT_NOP=n in both the host (lte_ble_gateway) and controller (hci_uart) and see if the error still appears.

Best regards,

Simon

Having encountered the same issue, I've tested with CONFIG_BT_WAIT_NOP=n on both sides, and that fixes the assertion failure.

An interesting side note is that on the nRF9160-DK, even with CONFIG_BT_WAIT_NOP=y, the assertion only fails during the first boot after powering on, while after resetting the nRF9160 the assertion succeeds.

Did you ever figure out a fix for this? I'm experiencing the same issue you just described

Hello, esisk. It seems like you were able to find a solution here https://devzone.nordicsemi.com/f/nordic-q-a/87208/nrf9160-ble-gateway-using-nrf52820. Right?

[esisk]

Yep thanks for responding Simon
