Hung up on advertising

[Lee Daniel Crocker]

I'm migrating an old (but working) app from the S110 5.2.1 (SDK 4.X) to the latest SDK9/S110 8.0. I've read the migration doc, and I'm following the examples carefully (specifically app_hids_keyboard, app_uart, and app_hrs). All my init functions are happy: timer, scheduler (with the new APPSH stuff), softdevice (using SOFTDEVICE_HANDLER_APPSH_INIT), everything comes up nicely. Scheduler works.

Then, I call ble_advertising_start(), I get a single BLE_ADV_EVT_FAST, then never another event of any kind. My phone can't see it advertising like it used to, and I never get any errors or anything--just quiet.

The major difference I noticed with my old code is that is has the sec_params_init() and responds to BLE_GAP_EVT_SEC_INFO_REQUEST, while most of the demos respond to that with a BLE_GAP_SEC_STATUS_PAIRING_NOT_SUPP. I never get that event in any case. I noticed that the device manager seems to make those similar security settings, but when I add it into the mix, I don't even get the first advertising event I was getting.

I'm really at a loss what to look for to debug this: If I get errors, I can see them; if I get events, I can see them. But I'm getting nothing.

I'm sorry, I just assumed you had testet the unmodified example first. Are you using a custom board or PCA10001? Either way it depends on what chip revision of the nRF51 you have on them. You need to compare the device markings of your chip/chips with Table 1 or Table 2 in the nRF51 Series Compatibility Matrix to figure out what revision you have. Then you check Table 4 to see what SoftDevices and SDKs that are compatible with your chips. I just tested SoftDevice s110 8.0.0 with an unmodified ble_app_hids_keyboard from SDK 9.0.0 on a nRF51422 revision 2 chip, and it advertises.
