Error on writing characteristic (133)

[michel]

Hi

I'm testing the nRF Toolbox for Android. But I get this error when I try to connect using the proximity feature:

I'm using the nrf51822 EK with the s110 ble_app_proximity and the phone is a Samsung Galaxy S4 with android 4.4.2

I have also made some debugging, but I don't know how to fix this problem:

Thanks

Hi Michel,

Once a while we saw this error code. It's not described in the Android BLE documentation. However, the error usually come from the Att table being cached. So if you turn off and on bluetooth on the phone, it should usually fix the issue.

If the error occurs programmatically (that you can reproduce it again and again) please let me know.

Example hex file that worked for me ble_app_proximity.hex

Hi Hung Bui,

I did power reset as you told me, but the error remains. Is the ble_app_proximity S110 v 7.0. I follow these steps:

1. Open nrftoolbox.
2. Select proximity feature.
3. Click on connect.
4. Select my device.
5. They bond.
6. Suddenly the error appears.
7. The connection get lost.

I have tried with the nrf master control panel for android and there is no problem. I can connect and discover services. I think that the problem is in the nrf toolbox app.
