s130_nRF51_2.0.1 ERROR_NO_MEM

[Aymen Rejeb]

Hello Nordic team,

I'm doing a migration of my nRF51822 (32 RAM / 256 Flash) application from SDK10 (s130_1.0.0) to SDK12.2.0 using the s130_2.0.1. So I took the experimental_ble_app_buttonless_dfu example with default memory mapping and started to add my custom services.

The service I'm trying to add contains 2 characteristics with max_lenght = 20 bytes for each of them. However when trying to add my custom service 128-UUID sd_ble_uuid_vs_add(&nus_base_uuid, &p_dfu->uuid_type) returns ERROR_NO_MEM (0x04), which was not the case with my app in SDK10 and s130_1.0.0 on the same chip!

Could this be a bug in the new soft-device? am I using the wrong example (I have to mention that I need to do the DFU, the DFU serivice is a must!)? or there might be a special configuration that I'm missing?

Many thanks in advance,

Ayman.

Hello Ayman,

Have you adjusted RAM allocation for BLE stack and ATT stack size during SoftDevice init? Here is something on the same topic (and there is much more on this forum, just search).
