Add PB-GATT to BLE_UART coexist

[SHawY]

Hi, 

I'm using nRF52840 with nRF5 SDK 16.0.0 and Mesh SDK 4.0.0.

I'm trying to add PB-GATT service to the ble_app_uart_coexist example. I set MESH_FEATURE_GATT_PROXY_ENABLED 1 and 
 MESH_FEATURE_PB_GATT_ENABLED 1, added the missing files and got this: 

00> <info> app: Debug logging for UART over RTT started.
00>
00> <error> app: ERROR 4 [NRF_ERROR_NO_MEM] at mesh_adv.c:147
00>
00> PC at: 0x0005A9D5
00>
00> <error> app: End of error report

I checked previous relevant questions it's might because of conflit of two advertising sets but didn't get any answers... Has anyone solved this?

Hi. 

The light switch examples supports PB-GATT, did you take a look at how this is added there?

Are you using multiple advertising sets? If the cause of the NRF_ERROR_NO_MEM is due to sd_ble_gap_adv_set_configure, NRF_ERROR_NO_MEM is returned because there is mot enough memory to configure a new advertising handle. Currently only one advertising set can be configured in the SoftDevice. The solution is to reuse the existing advertising handle you have.

Hi Joakim,

Thanks for answer. I can understand how the light switch example added PB-GATT and I'm trying to enable it in coexist example follow that.... I'm a little confuse about 'Currently only one advertising set can be configured in the SoftDevice'. Does that mean I need reconfigure or restart the device if I want to use multi advertising handles(for example, disable PB-GATT, restart and start BLE GATT after provisioned)? I assume the ble and mesh stack configured the advertising set separately in the coexist example, is it possible to reuse it?

hello,Joakim Jakobsen can you guide me how to add PB-GATT to the ble_app_uart_coexist example.

i have gone through light switch examples, but failed to integrate PB-GATT  to ble_app_uart_coexist example.

thank u
