Can't receive RX data in nus_data_handler - Error 128 (0x80)

[dimatteo]

Hello Nordic,

I'm trying to run nRF5_SDK_17.0.2_d674dde\examples\ble_peripheral\ble_app_uart (PCA10056, S140 softdevice) with default sdk_config.h. The master is nRF Connect app installed on 3 different Android phones:

* Samsung J5 with Android 7

* Samsung A40 with Android 9

* Samsung S10 Lite with Android 10 (updated to 11)

For J5 and A40 i'm able to handle all events in nus_data_handler and application works as expected. The issue occurs for S10 Lite when writing data to characteristic (the value is single byte!). I'm getting Error 128 (0x80): GATT NO RESOURCES in the app logs. I've changed MTU on BLE_GATT_ATT_MTU_DEFAULT (23) but it didn't solve the issue. I still can't recevie data from S10 in nus_data_handle. Additionally, I've launched sniffer and prepared appropriatelogs for J5 and S10 phones in WireShark. Any ideas how to fix it? Thanks!shark_write_s10_failed.pcapngshark_write_j5_success.pcapng

Please check out this case, where the GATT NO RESOURCES error on the phone is. I have not had time to check out your sniffer files yet, but will do so early next week.

Could you also provide a .hex file of the application you're running so we can test it on a Samsung S10 Lite on our side?

Best regards,

Simon

Thanks for your asnwer. I've read this topic but it didn't help me to solve the issue. I'm adding the application hex file. ble_app_uart_pca10056_s140.hex
